WORKSHEET-3 1. If you stop peddling your bicycle on a level road you observe that its speed decreases gradually. a. Why does the bicycle decrease gradually? b. Is there any force acting on it which tends to reduce its speed?
Answers
Answer:
When we stop pedalling a bicycle its speed slows down due to air resistance and force of friction between type of bicycle and surface of road.
So retardation force is created which stop the bicycle.
When the rider stops pedalling the bicycle, the force of friction between the tyres of bicycle and the road acting in the direction opposite to the direction of motion of the bicycle, opposes the motion of the bicycle and this force is now unbalanced, thus slowing down the bicycle.
