Question

When the surface of one body slides over another, in which direction does friction act?

पर्याय

• In the same direction as the motion

• Tangentially opposite to the relative motion

• Perpendicular to the surface

• At an angle of 45° to the surface

Answer 1

Tangentially opposite to the relative motion

Explanation:

Friction acts tangentially to the surfaces and is directed opposite to the relative motion between the two bodies.
