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. 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. When the rowing of a boat is stopped, the boat ...

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. WebMar 8, 2024 · FAQ on Friction Notes for Class 8 What is the frictional force? Frictional force is the force which opposes the relative motion when two objects are moving one over the other with their contact surfaces touching each other. There are several kinds of frictional force. If an object slides over the other then it is the case of sliding friction ...
