Force

In physics, a force is a push or a pull on an object that can change its speed, direction or shape.

Effects

A force can make a still object move, speed up or slow down a moving object, or change its direction. When forces are balanced, an object stays still or moves steadily.

Types

Common forces include gravity, friction, magnetism and the push of a hand. Isaac Newton's laws of motion describe how forces affect movement.
