Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the reaction force when a cannon fires a cannonball?

Back

The cannon moving backward.

Front

What does the law of inertia state?

Back

An object will continue moving at the same velocity unless an outside force acts on it.

Front

What is inertia?

Back

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

Front

What does Newton's First Law of Motion state?

Back

An object at rest or moving at a constant speed in a straight line will continue to do so until a net force acts on it.

Front

What type of friction is not moving?

Back

Static friction.

Front

What is the definition of force?

Back

A push or pull on an object that can cause it to accelerate.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.
