... Generally, however, the coefficient of friction is much more load-dependent. For some materials such as rubber this results from the materials deforming elastically rather than plastically at the points of contact. For other materials such as plastics this behaviour arises because they are visco-ela ...

Chapter 5 Notes
... If the force of gravity is being exerted on objects on Earth, what is the origin of that force? Newton’s realization was that the force must come from the Earth. He further realized that this force must be what keeps the Moon in its orbit. The gravitational force on you is one-half of a Third Law pa ...

... 6. Normal force is a force that acts in a direction perpendicular to the common contact surface between two objects. You must have a common surface area to have normal force. It is usually the same value as Fg but only on a horizontal surface! If the surface is sloped, they are not equal (and Fn is ...
