Front

What is Newton's First Law of Motion?

Back

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

Front

What is inertia?

Back

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

Front

What factors affect the amount of gravitational force between two objects?

Back

Mass and distance.

Front

What is mass?

Back

Mass is the amount of matter in an object.

Front

Do all objects have inertia?

Back

Yes, all objects with mass have inertia.

Front

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

Back

It continues to move at a constant velocity.

Front

What is an example of an object at rest?

Back

A parked car.

Front

What is an example of an object in motion?

Back

A rolling ball.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is an unbalanced force?

Back

A force that causes an object to change its state of motion.
