newtons laws

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 Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is force?

Back

A push or pull on an object resulting from the object's interaction with another object.

Front

What unit do we measure force in?

Back

Newtons (N)

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

If two boys pull on a rope with equal force, what will happen?

Back

They will not move at all.

Front

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

Back

It continues to move at a constant velocity.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is an example of Newton's Third Law?

Back

When you jump off a small boat, the boat moves backward as you move forward.
