Question

Consider a biker acclerating forward along a level road. Her wheels are rolling smoothly along the road without slipping. We need to be careful about the forces on the bike wheels. The forces between the road and the back wheel can be different from the forces between the road and the front wheel, and only the back wheel is connected to the drive chain and the pedals.

If we write out Newton's Second Law (F = M a) for the biker and the bike, which of the following forces is causing her and her bike's acceleration?

Gravitational force

Normal force with the road

Rolling friction with the road

Kinetic Friction with the road

Biker's force on the pedals

Static Friction with the road

Explanation / Answer

Rolling friction with the road Kinetic Friction with the road Biker's force on the pedals
