Question

Bicycle slows down when we stop pedaling. Because-

• A. there is net force on bicycle.
• B. there is backward force of friction from the ground.
• C. both a) & b).
• D. None

Answer 1

The correct option is C

both a) & b).

When we stop pedalling, the bicycle begins to slow down. This is again because of the friction forces acting opposite to the direction of motion. In order to keep the bicycle moving, we have to start pedalling again. It thus appears that an object maintains its motion under the continuous application of an unbalanced force.
