A moving bicycle comes to rest after sometime if we stop pedalling it. But Newton's first law of motion that a moving body should continue to move for ever, unless some external force acts on it. How do you explain the bicycle case?

Explanation

To explain why a moving bicycle comes to rest after stopping pedaling, despite Newton's first law of motion, we can break down the situation into a series of logical steps:

### Step-by-Step Solution:

1. **Understanding Newton's First Law**:
Newton's first law states that an object in motion will remain in motion at a constant velocity unless acted upon by an external force. This means that if no forces are acting on the bicycle, it should continue moving indefinitely.

2. **Identifying External Forces**:
