Newton's 3 Laws and Forces

Newton’s First Law of Motion

An object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force.

Newton’s Second Law of Motion

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

Newton’s Third Law of Motion

Whenever one body exerts a force on a second body, the second body exerts an equal and opposite force on the first.

Force

A push or pull on an object that can cause it to accelerate

Inertia

The ability of an object to resist a change in motion
