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 a net external 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. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

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

Front

What is a force?

Back

A push or pull exerted on an object.

Front

What is gravity?

Back

The attractive force that exists between all objects that have mass.

Front

What is mass?

Back

The amount of matter in an object, typically measured in kilograms.

Front

What is weight?

Back

The force exerted by gravity on an object, calculated as weight = mass × gravity.

Front

What is friction?

Back

The resistance that one surface or object encounters when moving over another.

Front

How does mass affect acceleration?

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's 2nd Law, force equals mass times acceleration (F = ma).
