Physics Question on Motion in a plane
A car moves on a circular road. It describes equal angles about the centre in equal intervals of time. Which of the following statements about the velocity of the car is true?
A
Magnitude of velocity is not constant
B
Both magnitude and direction of velocity change
C
Veiocity is directed towards the centre of the circle
D
Magnitude of veiocity is constant but direction changes
Answer
Magnitude of veiocity is constant but direction changes
Explanation
Solution
As body covers equal angles in equal time intervals of time, so its angular velocity and hence magnitude of linear velocity is constant.
