Newtons Laws of Motion

Front

What is Newton's 1st 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 2nd 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. This is often expressed as F = ma.

What is friction?

Back

A force that opposes the motion of an object.

Back

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

What is an example of Newton's 1st Law?

Back

A soccer ball will not move until someone kicks it.

Front

What is an example of Newton's 2nd Law?

Back

If you push a car and a bicycle with the same force, the bicycle will accelerate more because it has less mass.
