Which best describes inertia?

• how difficult it is to change an object's motion

• the size of an object

• how fast an object is moving

How are velocity and acceleration related?

• Acceleration is another word for velocity.

• Acceleration is the rate of change of velocity.

• Velocity is the rate of change in acceleration.

• Acceleration is always negative, and velocity is always positive.
