06: Friction
- #9Why do tyres have a better grip of the road while going on a level road than while going on an incline?Ans : The normal reaction force on a level road is mg, whereas on an inclined plane it is mg cos θ, which means that on an incline road the friction force between the tyre and the road is less. Hence, tyres have less grip on an incline plane and better grip on a level road.
