Newton's First Law of Motion

Front

What does Newton's First Law of Motion state?

Back

An object at rest will stay at rest, and an object in motion will stay in motion at the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to change its state of motion (either starting, stopping, or changing direction).

Front

True or False: An object at rest will stay at rest unless an unbalanced force acts on it.

Back

True

Front

True or False: A vector quantity has only magnitude and no direction.

Back

False

Front

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

Back

It will continue moving at the same speed and in the same direction.

Front

What is a force?

Back

A force is a push or pull that acts on an object.

Front

What is motion?

Back

A change in an object's position over time.

Front

True or False: A force can only be a push.

Back

False

Front

What is the difference between speed and velocity?

Back

Speed is how fast an object is moving, while velocity includes both speed and direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.
