Laws Of Motion Question 328
Question: It is difficult to move a cycle with brakes on because
Options:
A) rolling friction opposes motion on road
B) sliding friction opposes motion on road
C) rolling friction is more than sliding friction
D) sliding friction is more than rolling friction
Show Answer
Answer:
Correct Answer: D
Solution:
[d] When brakes are on, the wheels of the cycle will slide on the road instead of rolling there.
It means the sliding friction will come into play instead of rolling friction.
The value of sliding friction is more than that of rolling friction.
