Question

Four children were asked to arrange forces due to rolling, static and sliding frictions in a decreasing order. Their arrangements are given below. Choose the correct arrangement.

• A. rolling, static, sliding
• B. rolling, sliding, static
• C. static, sliding, rolling
• D. sliding, static, rolling

Answer 1

Answer: (C)

static, sliding, rolling

Answer 2

The correct arrangement of forces due to rolling, static, and sliding frictions in decreasing order is static, sliding and rolling.

Here's an explanation:

Static Friction: Static friction is the force that opposes the initiation of motion. It comes into play when an object is at rest and you apply a force to try to move it. Static friction is usually stronger than both sliding and rolling frictions.

Sliding Friction: Sliding friction occurs when two surfaces slide past each other. Once an object overcomes static friction and starts moving, sliding friction comes into play. It's generally weaker than static friction but stronger than rolling friction.

Rolling Friction: Rolling friction is the force that resists the motion of a rolling object. It is typically the weakest of the three types of frictions mentioned. When an object rolls without slipping, the rolling friction is generally less than sliding friction.

Therefore, The Correct option is (C): Static, sliding, rolling.
