Question

The maximum frictional resistance will be experienced by an object when the object is

• A. brought to rest from motion.
• B. being slided on a flat surface.
• C. about to start motion.
• D. falling from a height in air.

Answer 1

The correct option is C about to start motion.

Among the given cases, frictional resistance will be maximum when the object is about to start the motion. Static friction is greater than sliding friction and rolling friction. When the object is coming to rest from motion, it experiences sliding friction which is less than static friction.
