Question

Which of the following examples demonstrates rolling friction?

A. Between your shoes and the sidewalk as you walk.
B. Between your bike tires and the road as you ride.
C. Between a boat and the water as it sails.
D. Between two hands being rubbed together.

Answer 1

Rolling friction is demonstrated between bike tires and the road as you ride.

Step-by-step explanation:

The example that demonstrates rolling friction is B. Between your bike tires and the road as you ride.

Rolling friction is the force that resists the motion of a rolling object. It occurs when an object rolls over a surface without slipping. In the case of riding a bike, the friction between the bike tires and the road allows the bike to roll forward smoothly without sliding or skidding.

Another example where rolling friction is present is A. Between your shoes and the sidewalk as you walk. The friction between your shoes and the ground prevents you from slipping as you walk.
