Solution
Concept
Skidding versus slipping
Step-by-step solution
1. Skidding: the wheel moves along the road a greater distance than its rotation (wheels locked or partly locked). 2. Slipping: the wheel rotates without moving forward by the corresponding distance (wheel spin).
Explanation
When the distance travelled along the road is more than the circumferential distance the wheel rotates through, the wheel is skidding. Slipping is the opposite: the rotation is more than the forward movement.
Shortcut
Skid: path > rotation. Slip: rotation > path.
Common mistake
Mixing up skidding and slipping.
Correct answer: B) Skidding
