Purpose
In this experiment, you will lift a ball and drop it. You will determine and compare the potential energy of the ball before it’s dropped to the kinetic energy of the ball after right before it hits the ground.
Discussion
When an object is lifted, the work done to lift the object is transformed into potential energy [...]

A marble will roll on different paths, starting and ending at the same height. Students will predict and then measure the final velocities of the marble. Ramp A is the nearly horizontal ramp, and Ramp B dips down in the middle. Because the ramps start and end at the same elevation, a marble rolled on Ramp A will end with the same velocity as one rolled on Ramp B, even though they take different times to complete the trip.

Students will calculate the potential and kinetic energy of a popper toy using simple formulas. Potential energy is found by observing the maximum height. Kinetic energy is found by using a dynamics formula to find the popper’s starting velocity. Students will find that the popper reaches a greater height than it should, given the amount [...]

Students first measure the vertical displacement of a pendulum bob and calculate its potential energy compared to equilibrium. The predict the pendulum bob's maximum velocity and then measure the actual velocity at the bottom of the swing.

Chapter 12 Lab #42: Purpose: To explore conservation of energy for a rolling body.

In this lab using an Air Track, students will investigate elastic and inelastic collisions on an air track. Evaluate conservation of momentum and energy.

Chapter 9 Lab #28:
Using a pendulum, students will illustrate the principle of conservation of energy.
