Kinetic anergy and transfer

A student creates a ramp by stacking four blocks and then leaning a meter stick against it. She releases four different balls from the same position on the ramp and calculates their speeds. Based on the information in the table below, which ball would you predict to have the LEAST kinetic energy when it reaches the end of the ramp?

• Golf

• Tennis

• Baseball

• Softball

Students conduct an experiment using a toy car with the mass of 10g, a toy car with the mass of 20g, and a toy car with the mass of 30g. The students want to test the cars on a ramp and measure how far the cars traveled. Evaluate the information and determine the question they are trying to test with this experiment.

• Does the mass of the object influence the amount of potential energy?

• Does the amount of incline determine how far the car will travel?

• Does the mass of the car influence the amount of kinetic energy?

• Does the height of the ramp influence the amount of potential energy?

A diver standing on top of a diving platform that is 20 meters above the pool dives off the platform. Describe the transfer of energy that occurs during the fall.

• Kinetic energy changes to potential energy

• Chemical energy changes to potential energy

• Potential energy changes to kinetic energy

• Potential energy is destroyed. Kinetic energy is created
