Answer 1

Question:- Motion of a wheel of a car is  ?

a) Circular Motion

b) Rectilinear Motion

c) Periodic Motion

d) Both (a) and (b)

Answer:

(d) Both (a) and (b)

Explanation:

Motion of a wheel of a car is both (a) and (b) i.e. Rectilinear Motion and Circular Motion.

We know that when a car moves on the road with the help of wheels. The wheels basically moves in a circular motion but due to friction between road and wheel the wheels moves in forward(or backward according to direction of rotation) direction as well.  This is obvious from the motion of whole car.

Thus we conclude that Motion of a wheel of a car is both Circular and Rectilinear Motion.

Hence option d) is correct

Answer 2

D) Both a and b.
