Question

what are the factors affecting friction? explain with example

Answer 1

If two surfaces are rough than if they are smooth, then is important to action with a greater force. However, friction decreases with smoothness only to a degree;friction actually increases between two extremely smooth surfaces because of increased attractive electrostatic forces between their atoms.

Answer 2

Hi...

a) The materials that are in contact. The two materials and the nature of their surfaces. ...
b) The force pushing the two surfaces together. Pushing the surfaces together causes the more of the asperities to come together and increases the surface area in contact with each other..


Hope this helps u!
