Pushes and pulls are forces. Different types of forces can be contact or non-contact forces.
Forces can change an object's speed, direction, and/or shape.
Forces can be measured using a force meter, also known as a newton meter.
A force meter works by stretching a spring. As a downward force due to gravity increases, the spring stretches.
Forces are measured in newtons (N), named after Sir Isaac Newton.

Forces only act on moving objects.

Examples of forces being used to move stationary objects will be included.

Force - A force is a push or a pull. Forces can make objects move, change speed, change direction or change shape.
Force meter - A force meter is a piece of equipment used to measure the size of a force. It is also called a newton meter.
Push - A push is a force that moves an object further away.
Pull - A pull is a force that brings an object closer.
Newtons (n) - The size of a force is measured in newtons.
