Question
Which is the odd one out?
- Produces heat
- Riding
- Causes moving objects to stop
- Stopping vehicles
Hint:
Riding creates maximum friction respective to the motion of the tyres on the road.
The correct answer is: Riding
Riding is the odd one out.
- Friction produces heat when it has kinetic energy.
- Static friction takes place to stop a moving object and stop a vehicle.
- Riding creates maximum friction with the road.
