Question

what is frictional force for class 8​

Answer 1

Answer:

$\huge{\mathcal{\pink{A}\green{N}\red{S}\blue{W} {E}\green{R}}}$

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Answer 2

Friction is a force that comes into play when two surfaces come in contact with each other. The Frictional force or the force of Friction acts in the opposite direction of the motion of the object. The force of Friction opposes the relative motion between the surfaces of two moving objects.

Friction force

• The external force that opposes relative motion between 2 surfaces in contact.  

• Friction acts on the surface of contact of both the bodies.
