View related lesson
A

Greater than the coefficient of kinetic friction

 

B

Equal to the coefficient of kinetic friction

 

 

C

Smaller than the coefficient of kinetic friction

 

D

Unrelated to the coefficient of kinetic friction

Ask EduPadi AI for a detailed answer
Correct Option: A

Explanation: The coefficient of static friction (μs) is generally greater than the coefficient of kinetic friction (μk) for a given pair of surfaces. The static friction is higher because it needs to be overcome to initiate motion.
