Question

"When a car vehicle is moving with uniform velocity then the frictional forces on the vehicle by the road is zero"- Why the frictional force is zero and why not (mumg)? Explain in details.

Solution

Dear student,
As car is moving with the uniform velocity, therefore acceleration is zero and according to Newton second law of motion,
applied force on the car is zero and hence there will be no frictional forces on the vehicle.
