Types of Forces
Chantel Johnson
Push, Pull, Grip
These are contact forces which the agent has to be in contact with the receiver
Gravity
Attractive force between two objects that depends on the masses of the objects and the distance between them.
Friction
Forces that opposes the motion between two touching surfaces. Works against motion
Electrical
2 like charges repel. 2 opposite charges attract
Air Resistance
Force that opposes the motion of objects that move through the air.
Buoyancy
For an object to float, the upward buoyant force must be equal to the downward gravity force.
Air/Water Pressure
The outward force caused by the contained water or air.
Tension/Elastic
A force caused by a string or rope resulting in pulling.
Normal Force
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.
Noncontact Forces
Those that act at a distance such as gravity and magnetism.
