# Forces

## Push/Pull/Grip Forces

A force exerted no another object.

## Buoyant Forces

For an object to float, the upward buoyant force must be equal to the downward gravity force

## Air and Water Pressure

Air Pressure: Force exerted on a surface by the weight

Water Pressure: A force that makes a flow of water strong or weak

## Friction Forces

Force that opposes the motion between two touching surfaces. Works against motion.

## Air Resistance Force

Force that opposes the motion of objects that move through the air.

## Normal Force

The force perpendicular to an object's surface that results in support.

## Tension Forces

Being stretched tightly by forces acting from the opposite ends.

## Elastic Force

A force stretched or compressed but able to go back to its original shape or form.

## Electrical Force

Two like charges repel. Two opposite charges attract.

## Gravity Force

Attractive force between two objects that depends on the masses of the objects and the distance between them.
