Question

does newton's 3rd law apply for frictional forces? why or why not

Answer 1

Newton's Laws of motion are applicable on any set of coordinates, which are not accelerating. Newton's third law is no different. The frictional forces are of three kind: static, sliding and rolling.

Newton's Third law suggests that if a body A is applying a force Fa on a body B, then the body B will also apply the same amount of force Fb along the line of action of Fa to body A in opposite direction to Fa.

Thus, these pair of forces are acting on two different bodies whose surfaces are in contact. The frictional force also acts in the same way, Both the bodies in contact experience an equal and opposite amount of frictional force along the tangent to the surfaces in contact, wwhether it is static, siding or rolling.

Yes, Newton's 3rd law is applicable for the frictional forces.
