Newton's laws of Motion

Front

What is Newton's First Law of Motion?

Back

An object in motion will stay in motion, and an object at rest will stay at rest 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 mass?

Back

The amount of matter in an object.

Front

What is force?

Back

A push or pull resulting from the interaction of an object.

Front

What is acceleration?

Back

The change in speed (velocity) with respect to time.

Front

What is net force?

Back

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

Front

If a boy pulls a wagon with a net force of 6 N to the left and another boy pushes it with a force of 4 N to the left, what is the net force?

Back

10 N to the left.

Front

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

Back

The object will remain at rest or continue to move at a constant velocity.

Front

What is inertia?

Back

The tendency of an object to resist changes in motion.
