Frictional force is a contact force. Frictional force always acts between two moving objects, which are in contact with one another. Frictional force always acts opposite to the direction of motion. Frictional force depends on the nature of the surface in contact. why are there different amount of frictional force at different gear

Open in App

Solution

Force of kinetic friction remains same in every gear but when we change the gear, speed of the body increases.
