Question

Give 3 methods of increasing friction.

Answer 1

The Method of increasing friction are:-

[❶] Increase the fluid Viscosity.
[❷] By making the surface rough.
[❸] By increasing the mass of the object.

Answer 2

Answer:

• Friction is the force obtained when pressure is exerted between the two bodies.
• The back movement of a sliding object is held by friction.
• If there were no friction then we could not be able to run, jump in the forward direction.

The three methods of increasing friction are:

1. The surface of the object should be made rougher.
2. The imperfections of the surface are added.
3. Remove any liquid or lubricant.
