Notes on friction
WebMay 10, 2024 · Friction is a force that occurs between two surfaces, and it acts to impede motion. If the students suggest inertia as the reason why the cups do not slide, you might introduce Newton's first law of motion: An object at rest will stay at rest unless it is acted on by an outside force. WebFriction always works in the direction opposite to the direction in which the object is moving, or trying to move. Friction always slows a moving object down. The amount of friction depends on the ...

http://www.studyphysics.ca/2007/20/02_dynamics/26_friction.pdf WebOver here, the friction is some fraction of the perpendicular force that acts between two objects (we determine the fraction by a number known as the coefficient of friction). Generally, the force is independent of the contact area and does not depend on how fast the two objects are moving. Friction also acts in stationary objects.
WebFriction is a force that opposes relative motion between surfaces in contact. One of the simpler characteristics of friction is that it is parallel to the contact surface between … WebMar 29, 2024 · Friction is the force that resists the sliding of an object against another. Friction causes objects to slow down and eventually stop moving. Friction is not always a …
