Answer 1

Answer

Forces of Friction becomes More between two rough surfaces ..

Friction

• The opposing force that acts between two bodies in contact with each other is known as friction.

• It usually acts in the opposite direction to the motion of the object .

• Friction is more for rough surfaces than that of the smooth surfaces.

• More the force , more will be the fiction as intention of the friction is to stop the relative motion between the bodies.

Reason for More friction in rough surfaces !

• The rough surfaces show irregularity on their structure which is not present in the case of smooth surfaces.

• Due to uneven nature of the rough surface it is little hard for the object to exhibit motion in a smooth manner hence more force of friction is experienced by them.

• Teeth of both the objects present in contact with each other gets interlocked tightly hence restricting the motion of the object , which does not happen when we take smooth surface holding objects into consideration.
