A scooter generally slips on an oily road, because

Options

A. friction between tyres and road is large.
B. friction between tures and not sufficient.
C. inertia between tyres and road is large.
D. tyres of a scooter cannot rotate.

Explanation

**Step-by-Step Solution:**

1. **Understanding Friction**: Friction is the force that opposes the relative motion of two surfaces in contact. It is crucial for the movement of vehicles, as it allows tires to grip the road.

2. **Identifying the Scenario**: In this scenario, we are considering a scooter on an oily road. The presence of oil on the road significantly alters the frictional force between the tires and the road surface.

3. **Effect of Oil on Friction**: Oil creates a layer between the tire and the road, which reduces the amount of contact between the two surfaces. This leads to a decrease in the frictional force.

4. **Low Friction on Oily Roads**: When the friction is low, it is not sufficient to counteract the forces acting on the scooter, especially when accelerating or turning. As a result, the tires may lose grip and the scooter may slip.

5. **Conclusion**: Therefore, a scooter generally slips on an oily road because the friction between the tires and the road is very low, which is insufficient to provide the necessary grip for safe movement.
