Newton's First Law

Front

What is the tendency of an object to resist a change in motion called?

Back

Inertia

Front

What type of force must act on an object in motion to change its state of motion?

Back

An unbalanced force

Front

To which types of objects does the law of inertia apply?

Back

Both moving and nonmoving objects

Front

What is another name for Newton's First Law?

Back

The Law of Inertia

Front

If one object has twice the mass of another, what else does it have twice as much of?

Back

Inertia

Front

What does Newton's First Law state about an object at rest?

Back

An object at rest will stay at rest unless acted upon by an unbalanced force.

Front

How does mass affect inertia?

Back

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

Front

What is the relationship between inertia and motion?

Back

Inertia is the property that keeps an object in its current state of motion.

Front

Can an object in motion change its velocity without an external force?

Back

No, an object in motion cannot change its velocity without an unbalanced force acting on it.

Front

What happens to a moving object when no net force acts on it?

Back

It continues to move at a constant velocity.
