Describe how friction helps and how it creates a problem when you cycle.

Dear Student,
Friction helps in many ways when we ride a bicycle.
  • First of all we are able to ride because of friction between road and tyres of the cycle.
  • We are able to apply brakes due to friction.Becausse friction between a bicycle brake pad and the rim of a wheel causes the wheel to stop turning.
  • We are able to have a good grip on the handle bars due to friction
  • .It allows us to sit on the seat without slipping.
  • Friction keeps our feet on the pedals.
On the other hand friction also causes some problems while riding a bicycle.
  • There will be friction between the moving parts of the bicycle such as chain and gears.This makes it harder to ride and more energy is wasted.To avoid this we need to regularly apply lubricants on the chain and gears.
  • Friction causes wear and tear on the moving parts of the cycle and also wears down the tyres.
  • As we ride , a frictional force called air resistance opposes our movement.It also wastes more energy.
Regards..
