Question

what is friction explain it
​

Answer 1

Answer:-

Friction is the force that opposes the relative motion between the two surfaces of objects in contact. The force of friction always acts in the direction opposite to that of the applied force. Since friction is a type of force, it is measured in Newton (N).

When an object rolls over a surface, the force needed to overcome rolling friction is much less than that needed to overcome sliding friction.

Answer 2

Answer:

the property by virtue of which a force is created between two rough buddies which resistors the sliding of one body over the other is called friction...
