Front

What is Newton's First Law also known as?

Back

The Law of Inertia.

Front

What does it mean when the net force is 0?

Back

It means that all forces acting on an object are balanced, resulting in no change in motion.

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

It applies to both moving and nonmoving objects.

Front

What happens to objects at rest according to Newton's First Law?

Back

Objects at rest remain at rest unless acted upon by a force.

Front

What happens to objects in motion traveling at a steady rate in a straight line?

Back

They continue in that state until a force acts on them.

Front

What is inertia?

Back

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

Front

How does mass relate to inertia?

Back

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

Front

What is an example of an unbalanced force?

Back

A person pushing a stationary car to get it moving.

Front

What is the significance of the term 'steady rate' in Newton's First Law?

Back

It indicates that an object is moving at a constant speed in a straight line.
