This is because the force (friction) applied by the brakes on the car wheel can exceed the car tire’s traction coefficient (friction) on the road surface. When the car tyre starts to skid, friction with the road is further reduced, the brakes require so less force to keep the type locked, thus making the path traveled more than the circumferential movement.
Hence, the correct option is (B)

Skidding vs Slipping:
Skidding and slipping are two different types of motion that can occur when a vehicle is moving on a road surface. Skidding occurs when the vehicle's wheels lose traction with the road surface and slide sideways, while slipping occurs when the wheels spin without moving the vehicle forward.
Causes of Skidding:
Skidding can occur for a variety of reasons, including:
- Excessive speed: When a vehicle is traveling too fast for the road conditions, it may lose traction and skid.
- Wet or icy roads: When the road surface is wet or icy, it can be difficult for the vehicle's tires to maintain traction.
- Braking too hard: If the driver applies the brakes too hard, it can cause the wheels to lock up and skid.
- Cornering too quickly: If the driver takes a corner too quickly, it can cause the vehicle to lose traction and skid.
Effects of Skidding:
When a vehicle skids, it can be difficult for the driver to maintain control. The vehicle may slide sideways or spin out of control, which can lead to accidents or collisions with other vehicles or objects.
Prevention of Skidding:
To prevent skidding, drivers should:
- Adjust their speed to match the road conditions.
- Use caution when driving on wet or icy roads.
- Avoid braking too hard, especially on slippery surfaces.
- Take corners slowly and carefully.
Conclusion:
In summary, skidding is a type of motion that occurs when a vehicle's wheels lose traction with the road surface and slide sideways. It can be caused by a variety of factors, including excessive speed, wet or icy roads, hard braking, or cornering too quickly. To prevent skidding, drivers should adjust their speed, use caution on slippery roads, avoid hard braking, and take corners slowly and carefully.
