Types Of Forces
Zoe Collis
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.
Friction Force
Forces that opposes the motion between two touching surfaces. Works against motion.
Electrical Force
Two like charges repel. Two opposite charges attract.
Air Resistance
Force that opposed the motion of objects that move through the air.
Buoyancy Forces
For an object to float, the upward buoyant force must be equal to the downward gravity force.
Air/Water Pressure
Force that opposes the motion of objects that move through the air.
Tension/Elastic
Force that is transmitted through a string, rope, cable or wire when it is pulled tight by forces acting from opposite ends.
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.
