The Friction on the road during rainy season will be (b) Less

Let us see, how the friction decreases on rainy season.

  • The co-efficient of static friction (μ) between the road and the tyres plays an important role in controlling the motion of a car.
  • If the value of the coefficient is small, it becomes difficult to accelerate or steer the car. In some cases the wheels may start to skid, and the driver may lose control. Such a situation arises while driving on a wet road at high speed, as, the coefficient of static friction between the tyres and the road falls appreciably when this road gets wet.
  • Frictional Force = μN ( where μ = coefficient of friction; N = Normal Reaction)
  • So when the value of μ decreases, the value of frictional force      

      decreases.

What is friction?

  • Friction is the force of resistance that is produced when there is relative motion between surfaces.
  • Frictional force is a contact force.
  • Force of friction is directly proportional to coefficient of friction.
  • While driving a car, the frictional force helps in steering and braking the wheels. When there is rain, the coefficient of friction becomes too less because water comes in between the contact of two rough surfaces.
  • When co-efficient of friction becomes less, frictional force also decreases and it becomes difficult to drive as wheels start skidding.
