Front

What is Newton's First Law of Motion?

Back

Front

What is inertia?

Back

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

Front

What does Newton's Second Law of Motion state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for calculating force?

Back

Force = Mass x Acceleration (F = ma)

Front

What is an unbalanced force?

Back

A force that causes an object to change its motion.
