Newton's First Law of Motion

Front

What does Newton's First Law of Motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by an unbalanced force.

What is inertia?

Back

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

What is an unbalanced force?

Back

An unbalanced force is a net force that causes an object to accelerate.

Front

How does mass affect inertia?

Back

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

Front

What is the relationship between net force and acceleration?

Back

Net force is directly proportional to acceleration, as described by Newton's Second Law (F=ma).

Front

What happens to an object in motion when no net force acts on it?

Back

It continues to move at a constant velocity.

Front

What is the net force acting on an object if the forces are balanced?

Back

The net force is zero.

Front

Can an object be in motion if no forces are acting on it?

Back

Yes, if it is already in motion, it will continue to move at a constant velocity.

Front

What is an example of an unbalanced force?

Back

A person pushing a stationary car to get it moving.
