Question

State one way of increasing friction.

Answer 1

One of the important ways of increasing friction is making the surface rough.

1. The friction between two surfaces in contact depends on their surface roughness.
2. Rougher the surfaces, the more will be friction.
3. For example, spikes on the shoes increase the roughness of the sole of the shoe which increases the friction between the ground and the shoe.
4. A rough grip of the bat handle increases the friction between the hands and the handle which gives better control over the bat.
