Potential & Kinetic Energy Ball Drop Lab
Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data to calculate average bounce heights and coefficients of elastici In this activity, students examine how different balls react when colliding with different surfaces. They learn how to calculate momentum and understand the principle of conservation of momentum. Imagining themselves arriving at the Olympics gold medal soccer game in Rio, Brazil, students begin to think about how engineering is involved in sports.
After a discussion of kinetic and potential energy, an associated hands-on activity gives students an opportunity to explore energy-absorbing mate Students examine how different balls react when colliding with different surfaces, giving plenty of opportunity for them to see the difference between elastic and inelastic collisions, learn how to calculate momentum, and understand the principle of conservation of momentum.
Could you play tennis with a baseball or soccer with a basketball? Listen to student responses. What are all the different sports that are played with balls? Possible answers: Volleyball, soccer, football, softball, baseball, ping pong, wiffle ball, bowling, dodge ball, golf, jacks, tennis, croquet, raquetball, squash, tetherball, etc. What are some differences and similarities among the balls used for different sports? How do the materials and design of a ball affect its characteristics?
A soccer ball is designed to be bouncy, flexible and full of air, making it great to be kicked down a soccer field without injuring players. A bowling ball is dense, heavy and hard so that it can be rolled down a bowling alley to hopefully get a strike rather than a gutter ball. Each ball is designed with specific materials, making it appropriate for a particular sport.
When engineers are given a design task, whether it is designing a new volleyball that can bounce twice as high or a new airplane or skyscraper, they must study and analyze the properties of the materials they would like to use. What might be some material properties that they consider? Possible answers: Weight, strength, hardness and flexibility.
Do you think it is important to understand materials and their properties, especially in the design of a ball used in a game? Well, imagine being the goalie in a soccer game that uses a bowling ball instead of a soccer ball.
Iron Bracket use to constant the height, and clamp use to stable the Smart Timers attached on the Iron Bracket. The Smart Timers is use to count the amount of time. Target pad is part of the Smart Timers, it use to when ball fall on it, it will back to Smart Timers to make it stop timing.
Photostat also the part of the Smart Timers, it use to back to Smart Timers the ball start drop, to make Smart Timers start timing. Procedure First check the height is CACM; place the Photostat with the bar and attached it to the lower clamp on the main bar-stand.
Place the plug from the Photostat to the 1 spot on the smart timer. Tightened the clamp so that it is perpendicular to the main bar stand. Connect the plug from the pad to the spot on 2 spots on the smart timer. Don't use plagiarized sources.
Do this 10 times and take an Data The following chart details the ten times trials of the experiment and includes an average of the ten times trials. It has a considerable error with prediction. The new hypothesis need to make sure the ball is drop from the same height, use hands to begin the drops will be have too much error, choose a heavier ball, to reduce the impact of air resistance.
Shorten the connect line both between the Photostat and smart timers, and pad and smart timers. Error Analysis The result has a considerable error with prediction. The most likely cause is air resistance and height not content. Use hand to start drop the ball is hard to constant the height, here will have some error, and plastic ball may too light, it is susceptible to get effect by the air resistance. Also the smart line connect line data transmission time will be effect the result, but this time is almost negligible, and under the present conditions, it is no way to improve that much.
The data result with prediction has about Conclusion The experiment is to calculate the acceleration of gravity using the Smart Timers. The error make the result with forecast has a large gap. Air resistance and height is just relatively constant are the most reasons.
Set a constant height will be better than use hands to drops the ball. Change the yellow plastic ball to an iron ball or other heavier ball will be much decreases the effect from air resistance. And have more tests will be better to confirm the results, if each personal do the ten times, then compare the each result, more tests is help to reduce errors.

Hi there, would you like to get such a paper?In the construction of railways, in the building of bridges and houses, account is always taken of the expansion of materials. Because when something gets hotter, it also increases slightly in size. The Leiden professor Willem Jacob 's Gravesande devised this gadget in order to demonstrate the effect to his students. The ball is first heated so that it expands to the point where it no longer fits through the ring.
Next the ball is placed on the ring, where it continues to cool until it fits in it again. At that moment the ball suddenly drops down without anyone having given it a helping hand! And he succeeded pretty well, since ''s Gravesande's ball and ring' is still one of the best-known demonstration experiments. As a basis for understanding this concept:. Students know heat flow and work are two forms of energy transfer between.
Students know that the work done by a heat engine that is working in a cycle is. Students know the internal energy of an object includes the energy of random. The greater the temperature of the object, the greater the energy of motion of the. Students know that most processes tend to decrease the order of a system over. Students know that entropy is a quantity that measures the order or disorder of a.

Product Description Standards NEW This lab engages students in all parts of the scientific method while exploring the ideas of potential and kinetic energy.
Log in to see state-specific standards only available in the US. Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.
Emphasis is on descriptive relationships between kinetic energy and mass separately from kinetic energy and speed. Examples could include riding a bicycle at different speeds, rolling different sizes of rocks downhill, and getting hit by a wiffle ball versus a tennis ball.
Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object. Examples of empirical evidence used in arguments could include an inventory or other representation of the energy before and after the transfer in the form of temperature changes or motion of object. Assessment does not include calculations of energy. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.
Examples of experiments could include comparing final water temperatures after different masses of ice melted in the same volume of water with the same initial temperature, the temperature change of samples of different materials with the same mass as they cool or heat in the environment, or the same material with different masses when a specific amount of energy is added.
Assessment does not include calculating the total amount of thermal energy transferred. Total Pages.Buggy Ball Drop Lab
Report this Resource to TpT. Reported resources will be reviewed by our team. Add one to cart.Please note: This is a fairly nice lab report of an experiment that should provide a guide to you for producing your own lab reports. It was written by students who took this course. Our purpose is to determine as precisely as possible how much energy is lost in the bounce of the ball and to observe how well the energy is conserved throughout the flight.
We believe that if the air resistance is neglected, then the ball that is dropped should conserve total energy as it falls.
However, because the ground is not a totally elastic surface, some of the energy will be lost. We will therefore observe the total energy as a function of time so as to determine whether the energy is lost in the actual bounce of the ball into an inelastic surface, or due to air friction. First we needed to set up the equipment which contained a motion sensor and a golf ball. The golf ball was weighed and the height of the sensor, h, was measured with the digital meter on the sensor.
The distance we are actually measuring, though, is the distance between the ground and the sensor because we are subtracting the distance from the motion sensor to the ball. We need to correct for the diameter of the ball because the distance from the motion sensor to the top of the ball is what the sensor is measuring, not the distance from the sensor to the ground. In order to do this we subtracted the diameter of the ball from h. Now that we were ready to begin the experiment, we held the ball below the sensor enough so its position is recorded and we began the recording and let the ball drop.
A graph was created in Science Workshop displaying our data. More graphs and tables were then created. Kinetic energy is the energy an object has while in motion. An object loses kinetic energy each time it hits a non-elastic surface. Kinetic energy is dependent upon the mass of the object and the velocity the object is moving with. Potential energy is the possible amount of energy an object has before any movement.
Potential energy is dependent upon the mass of the object, acceleration due to gravity and the height of the object. Each time the object falls it loses potential energy and each time it returns it gains potential energy. This is because potential energy is lowest when the ball hits the ground.Planetary exploration vessels like Voyager I and Voyager II made use of propulsion maneuvers which gained energy from the planets and moons they passed.
Such maneuvers are really elastic collisions where the objects involved never hit each other but are affected by gravity as they approach. An extreme case of such a propulsion maneuver is like the double ball drop. Double Ball Drop. If a light ball like a ping-pong ball is dropped along with a heavy ball like a large superball, the small ball rebounds with a remarkably high velocity, theoretically approaching three times the velocity with which the balls strike the surface.
The analysis involves the nature of head-on elastic collisions and in particular the case of a light projectile hitting a heavy target. Slingshot orbits used in space exploration have features in common with this situation even though the objects involved never touch each other.
Galileo's Leaning Tower of Pisa experiment
The rebound velocity of 3v for the small ball implies that its kinetic energy is nine times its incoming kinetic energy since the kinetic energy is proportional to the square of the velocity. Since the gravitational potential energy is proportional to the height and the kinetic energy is all converted to potential energy at the peak of the motion, it will rise to height 9h.
Index Collision concepts. Analysis of Double Ball Drop The two slightly separated balls dropped from the same height are seen by a ground observer to approach the surface with velocity v. A ground observer sees the larger ball hit and bounce up with velocity v while the smaller one still approaches. An observer on the larger ball would see the smaller one approach with velocity 2v.
That observer would see the surface receding with velocity v. Assuming perfectly elastic collisions and that the large ball is much more massive than the small one, the observer on the large ball will see the small one bounce back with velocity 2v. A ground observer would see the velocity of the small ball as 3v. Gravity-Assist or Slingshot Orbit Planetary exploration vessels like Voyager I and Voyager II made use of propulsion maneuvers which gained energy from the planets and moons they passed.
A famous example of the use of such maneuvers is the exploration of Comet G-Z. The Voyager missions also made several energy-boosting flybys of planets on their paths through the solar system. The spacecraft Mariner 10 made several slingshot maneuvers in its exploration of Venus and Mercury. More "gravity assist" maneuvers. Index Collision concepts Elastic collisions. More Gravity-Assists The use of a gravity-assist or "slingshot" orbit has been of great benefit in the exploration of the solar system.Although dropping a ball and letting it bounce seems like a common everyday occurrence, there are numerous forces at work in this scenario.
Several different projects can reveal transfer of energy or acceleration taking place. When a dropped ball collides with the ground, its kinetic energy is transferred into potential energy as the ball compresses. Then, as the ball's elasticity causes it to expand, potential energy is transformed back into kinetic energy in the form of the ball bouncing back up off the ground.
To see this transfer of energy, drop several different types of balls onto the ground from the same height and see how high each type of ball rebounds. Determine which balls are the most efficient at transferring kinetic energy to potential energy and back again.
Potential & Kinetic Energy Ball Drop Lab
Energy can be transferred from kinetic to potential, and it can also be transferred during the course of a collision. To observe this transfer of energy, start by dropping a basketball from a given height and then measuring how high it bounces. Next, drop the basketball from the same height, but this time with a racquetball placed directly on top of it. Record the height of the basketball on this drop and compare it to the height seen on the first drop.
A ball will accelerate toward the ground after being dropped, and you can track this acceleration using a video camera and a projector. Start by video recording a person dropping a ball and that ball hitting the ground at a rate of about 60 frames per second.
All the action should take place in the same frame. Next, project the video of the falling ball onto a large sheet or multiple sheets of paper taped to a wall. Then plot the ball's fall one frame at a time. It should be evident that the ball moves farther from frame to frame the closer to the ground it gets. Galileo famously showed that all objects fall at the same rate by dropping two cannonballs with different weights off the Leaning Tower of Pisa.
He also proposed a thought experiment to demonstrate the same concept. To conduct this thought experiment, tie a large ball to a smaller ball. Drop both balls simultaneously and see how long they take to hit the ground.
Then, disconnect the two balls and drop them simultaneously again. According to Galileo, the amount of time for the "joined" drop and the the two individual balls should be the same, as neither ball was pulling up or down on the other one while the two were attached.
