What does friction occur ?????
plz help me....
Answers
Explanation:
Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.
when a ground or surface become slippery after rain or water splashing it is made rough by spreading sand to increase the friction. To decrease friction: (i) Friction between two surfaces can be decreased by using lubricants. (ii) Friction between two surfaces can be reduced by polishing them
Methods for decreasing friction:
Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.
Lubrication is another way to make a surface smoother. ...
Make the object more streamlined. ...
Reduce the forces acting on the surfaces. ...
Reduce the contact between the surfaces.
Everyday Examples of Sliding Friction
Rubbing both hands together to create heat.
A sled sliding across snow or ice.
Skis sliding against snow.
A person sliding down a slide is an example of sliding friction.
A coaster sliding against a table.
A washing machine pushed along a floor.
An iron being pushed across material.

when two bodies are rubbed
Explanation:
because when we rub two bodies there come friction
