Newton's Laws Review

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest unless acted on by an unbalanced force (inertia).

Front

What is Newton's Second Law of Motion?

Back

F = ma (Force equals mass multiplied by acceleration).

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the definition of net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What is inertia?

Back

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

Front

What is air resistance?

Back

The upward force that opposes the weight of an object falling through the air.

Front

What happens to a penny and a feather dropped from the same height in a vacuum?

Back

They fall at the same rate.

Front

What is terminal velocity?

Back

The constant speed that a freely falling object eventually reaches when the resistance of the medium prevents further acceleration.

Front

How does mass affect acceleration according to Newton's Second Law?

Back

As mass increases, acceleration decreases if the same force is applied.

Front

What is momentum?

Back

The product of an object's mass and its velocity.
