Explain the various types of friction
Answers
Hola...mate ...☺️
here is ur ans ☺️
Two type of friction
- Static friction
- Rolling friction
the force of friction which exactly counterbalance the applied force when the body is at stationary state is known as static friction...
follow me ❤️
The various types of friction:
- Rolling Friction
- Fluid Friction
- Static Friction
- Sliding Friction
Rolling Friction is, the force of friction that comes into play when one body rolls over the surface of another body. It is (much) less than the (force of) sliding friction.
A substance (like a liquid) that can flow easily; it has no fixed shape. It takes the shape of it's container.
We call the force of friction as 'static friction' when it exists between two surfaces (in contact) between which there is no relative motion. In other words, the force of friction, which balances the applied force during the stationary state of body, is static friction.
We call the force of friction, between two objects, when one of them is sliding over the surface of the other, as the (force of) sliding friction between them. Sliding friction is (a little) smaller than the static friction between the same two surfaces.
