# Forces

## Buoyant Force

A Buoyant force is an object floating in water or air. ## Air or Water Pressure

Air or water pressure is the pressure exerted by a fluid or air at any point inside. ## Friction

Friction is the force that opposes the motion between two surfaces. ## Air Resistance

Air resistance is the force that opposes the motion of object that move through the air. ## Normal Force

A normal force is the force that is perpendicular to an objects surface that results in support. ## Tension/Elastic Force

Tension/elastic force is the force cause by a string, spring, or, rope resulting in stretching or pulling. ## Electrical Force

Electrical force is the force where two positive charges will repel, as will two negative charges. A positive and negative charge attracted. ## Push/Pull/Grip Force

This is the force where exerting a specific motion on an object.

## Gravity

Gravity is an attractive force between two objects that depends on the masses of the objects and the distance between them.
