Compare static friction and sliding friction.

Correct option is B

The correct answer is (b) Sliding friction is slightly smaller than the static friction.
· Static friction is the frictional force that must be overcome to start moving an object at rest.
· Sliding friction (also known as kinetic friction) is the frictional force acting when the object is already in motion. Static friction is generally slightly greater than sliding friction because more force is needed to initiate movement than to maintain it.
· Once an object starts sliding, the frictional force decreases slightly, making it easier to keep the object moving.
Information Booster:
· Static friction prevents an object from starting to move until a certain threshold force is applied.
· Sliding friction acts when an object is already in motion and is typically less than static friction due to the momentum and reduced surface adhesion.
· The reduction in friction after the object starts moving is why pushing or sliding objects initially requires more force.
