Compare rolling friction and sliding friction.

Correct option is C

The correct answer is (c) Rolling friction is smaller than the sliding friction.
· Rolling friction occurs when an object rolls over a surface, while sliding friction occurs when an object slides over a surface. Rolling friction is generally much smaller than sliding friction because the area of contact between the rolling object and the surface is smaller, leading to less resistance. This is why wheels and ball bearings are used in many applications to reduce friction and make movement easier.
Information Booster:
· Rolling Friction: Experienced when an object rolls across a surface, such as a ball rolling on the ground.
· Sliding Friction: Experienced when an object slides across a surface, such as a box being pushed across the floor.
· Friction Comparison: Rolling friction is typically about 1/10th to 1/100th the magnitude of sliding friction.
