Newtons First Law

Front

What is Newton's First Law known as?

Back

The Law of Inertia.

Front

What does Newton's First Law state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is inertia?

Back

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

Front

What type of forces cause a change in an object's motion?

Back

Unbalanced forces.

Front

What is the normal force?

Back

The normal force is the support force exerted upon an object that is in contact with another stable object.

Front

What happens to an object if the net force acting on it is zero?

Back

The object will maintain its current state of motion, either at rest or moving at a constant velocity.

Front

What is an example of balanced forces?

Back

Two people pushing a car in opposite directions with equal force.

Front

What is an example of unbalanced forces?

Back

A person pushing a stationary car, causing it to move.

Front

How does mass affect inertia?

Back

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

Front

What is the relationship between force and motion according to Newton's First Law?

Back

A net external force is required to change the motion of an object.
