Friction class 11 notes
Webfriction, force that resists the sliding or rolling of one solid object over another. Frictional forces, such as the traction needed to walk without slipping, may be beneficial, but they also present a great measure of opposition to motion. About 20 percent of the engine power of automobiles is consumed in overcoming frictional forces in the moving parts. The major … Web2. Static friction is always greater than kinetic friction. This is due to inertia – An object at rest tends to stay at rest while an object in motion tends to continue moving. 3. Friction increases as the force between two surfaces increases. Friction depends on the nature of the materials coming into contact with each other.

WebApr 15, 2024 · Friction is a type of force that opposes motion. It is that force that always acts in a direction opposite to that of the applied force. In the case of a ball freely rolling on the ground, the ball eventually comes to stop, because of the force of friction that acts between the ball and the ground.
