When a rickshaw seat cover is smooth, you slip when brakes are applied suddenly because there’s less friction between your body and the seat. Friction is the force that opposes motion between two surfaces. A smooth surface provides less friction, so when the rickshaw brakes, your body, due to inertia (resistance to change in motion), tends to continue moving forward, while the seat stops abruptly.
Here’s a more detailed explanation:
Friction:
Friction is a force that opposes motion when two surfaces are in contact. It arises from the irregularities on the surfaces, making it difficult for them to slide past each other.
Inertia:
Inertia is the tendency of an object to resist changes in its state of motion. An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same speed and direction.
Smooth Surfaces and Friction:
Smooth surfaces have fewer irregularities, resulting in lower friction.
Rickshaw Brakes and Slipping:
When the rickshaw brakes suddenly, the seat stops moving, but your body, due to inertia, continues to move forward. If the seat cover is smooth, there’s little friction to hold you in place, causing you to slip.
