Front

What is the effect of friction on motion?

Back

Friction acts against the motion of an object to slow it down.

Front

Back

Greater mass results in less acceleration for the same force.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration.

Front

What happens to an object in motion if no net force acts on it?

Back

It continues to move at a constant velocity.
