   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.

   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 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 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).

   The magnitude of the frictional force has two forms: one for static situations (static friction), the other for situations involving motion (kinetic friction). What follows is an approximate empirical (experimentally determined) model only.

   friction refers to cases in which one surface moves relative to the other one, such as when a box slides across the floor, while static friction refers to cases in which the surfaces do not move relative to each other, such as when a person is pushing on a stationary heavy

   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.
