What is inertia?

• The force needed to get an object to move.

• A measurement of how much matter is in an object.

• The tendency of an object to stay at rest or in motion until another force causes it to change direction, slow down, or stop.

• The measurement of change in an object's velocity or speed.

What is acceleration?

• The force needed to get an object to move.

• A measurement of how much matter is in an object.

• The resistance of motion when one object rubs against another.
