What is inertia?

• The amount of matter in an object

• A push or pull resulting from the interaction of an object.

• The tendency of an object to resist changes in motion

• A ratio of the amount of mass to the amount of acceleration

What is Mass?

• The amount of matter in an object.

• A push or pull resulting from the interaction of an object.

• The change in speed (velocity) with respect to time.

• The tendency of an object to resist changes in motion (things want to keep doing what they are already doing).

• 100 N

• 200 N
