• A 5 gram marble rolling at 3 m/s
• A 5 gram marble sitting on top of a 50 meter hill
• A 4 gram marble rolling at 10 m/s

Back

Front

What is the stored energy an object has relative to its position and ability to move based on gravity?

Back

Potential gravitational energy

Front

What energy is released when an object returns to its original shape after being deformed?

Back

elastic potential energy

Front

How does friction impact a car rolling on the floor?

Back

It causes the car to lose its kinetic energy

Front

What is true of inertia and momentum?

Back

An object sitting still has inertia but not momentum
