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 unless acted upon by a net external force.

What does 'inertia' mean?

Back

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

Front

What is an example of inertia?

Back

A passenger lurching forward in a car when it suddenly stops.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object depends on the mass of the object and the amount of force applied (F=ma).

Front

What does 'force' mean in physics?

Back

A push or pull on an object that can cause it to change its velocity.

Front

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

Back

It takes more force to push a heavy car than a light lawnmower.

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is an example of Newton's 3rd Law?

Back

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

Front

What is 'friction'?

Back

Friction is a force that opposes the motion of an object.

Front

What is an example of friction?

Back

A ball rolling on the ground slows down due to friction with the surface.
