Push/Pull/Grip Force

These are contact forces that require the agent to be in contact with the receiver.

Gravity Force

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

Air/Water Pressure

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

Normal Forces

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

Contact Forces

Those that require the agent that causes the force to be in direct contact with the object.

Non-contact Forces

Those that act at a distance examples, gravity and magnetism.
