Question

Two boys are riding their bicycles on the same concrete road. One has new tyres on his bicycle while the other has tyres that are old and used. Which of them is more likely to skid while moving through a patch of the road which has lubricating oil spilt over it?

Answer 1

Frictional force:

1. Friction is the force that prevents one solid object from sliding or rolling over another.
2. Frictional forces, such as the traction required to walk without slipping, are beneficial, but they also present a significant amount of resistance to motion.
3. A bicycle with worn-out tyres is more likely to skid.
4. The boy with the worn tyres is more likely to slip because the tyres have less friction, which is insufficient to travel on the oily road.
