Kinetic and potential energy
Main lesson
Kinetic energy: mass and speed
Use this for “What has a bigger effect on kinetic energy, doubling the speed or doubling the mass?”
A pendulum trades energy
Use this for “Where is the pendulum fastest, and where does it have the most potential energy?”
Kinetic or potential energy?
Use this for “Is a rolling skateboard’s energy kinetic or potential?”
