"It is difficult to move a cycle along the road with its brakes on". Why?

Explanation

To understand why it is difficult to move a cycle along the road with its brakes on, we can break down the explanation into a few key steps:

### Step 1: Understanding Friction
Friction is the force that opposes the motion of an object. There are two main types of friction relevant to this situation: static friction and kinetic friction. However, in the case of a bicycle, we also need to consider rolling friction.

### Step 2: Types of Friction
- **Rolling Friction**: This is the friction that occurs when an object rolls over a surface. It is generally much less than static or kinetic friction, which makes it easier to move rolling objects.
- **Sliding Friction**: This occurs when two surfaces slide against each other. Sliding friction is usually greater than rolling friction.
