Potential Energy, Kinetic Energy, Average Speed and
Final Speed

The blue
track will have a The red track will
have a slower average speed and will reach the bottom later. Both tracks
will have the If the ball
starts from rest you can calculate the final velocity by using this equation:
The acceleration due to gravity (9.8
m/s2) = The drop measured in meters = If a ball is moving, you must include kinetic
energy and potential energy in your calculations. |
