Force/Motion

A force is a _______ or a _______.

• push, pull
• kinetic, potential
• gravity, friction
• see, saw

_______________ is the energy of motion.

• Potential energy
• Kinetic energy
• Friction
• Gravity

When a roller coaster moves down a ramp

• kinetic energy changes to potential energy
• electrical energy changes to light energy
• potential energy changes to kinetic energy
• gravity is not involved

The tendency of an object to stay in motion or at rest is called 

• velocity
• acceleration
• speed
• inertia

Which of the following describes energy?

• the ability to remain in motion
• the ability to do work
• the ability to pull objects down
• the ability to change states

When a ball rolls down a hill
