A push or pull on an object.

Front

What is motion?

Back

The change in position of an object over time.

Front

What is the relationship between mass and force according to Newton's second law?

Back

Force equals mass times acceleration (F = ma).

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is balanced force?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.
