   Three kinds of friction: • Static friction: acts to prevent motion, so points opposite to the direction the object would move in the absence of friction • Kinetic friction: appears when an object slides across a surface; points opposite to the direction of motion • Rolling friction: one surface rolling over another KJF §4.3, 5.5 3

   List the various types of friction. Calculate the magnitude of static and kinetic friction, and use these in problems involving Newton’s laws of motion. When a body is in motion, it has resistance because the body interacts with its surroundings. This resistance is a force of friction.

   Friction is a force that always exists between any two surfaces in contact with each other. There is no such thing as a perfectly frictionless environment. Even in deep space, bits of micrometeorites will hit a moving object, causing some friction (although it is incredibly small).

   Friction is a force that resists the movement of two contacting surfaces that slide relative to one another. This force acts tangent to the surface at the points of contact and is directed so as to oppose the possible or existing motion between the surfaces.

   Friction is a force that is around us all the time that opposes relative motion between surfaces in contact but also allows us to move (which you have discovered if you have ever tried to walk on ice). While a common force, the behavior of friction is actually very complicated and is still not completely understood.

   Friction. I. Theory. Friction is the resisting force encountered when one surface slides over another; this force acts along the tangent to the surfaces in contact. The force necessary to overcome friction depends on the nature of the materials in contact, their roughness or smoothness, and the normal force, but not on the area of contact.
