Force II PPT
... TENSION aka FT • is the magnitude of the pulling force exerted by a string, cable, chain, or similar object on another object. • It is the opposite of compression. It is a “response force” • That is to say, if one pulls on the rope, the rope fights back by resisting being stretched • Ropes, string ...

Forces and Motion
... Objects in motion tend to stay in motion and objects at rest tend to stay at rest unless acted upon by an unbalanced force. Newton’s Second Law: Force equals mass times acceleration (F = ma). Newton’s Third Law: For every action there is an equal and opposite reaction. ...

Big Idea
... Concept: When two surfaces of objects are in contact with each other, the force of friction between them depends on the nature of the materials in contact and the normal force. Competency: Construct a free body diagram indicating the magnitude and direction of the forces on an object and use informa ...
