Question

A car moves on a circular road describing equal angles about the centre in equal intervals of time. Which of following statements about the velocity of car are not true?

• A. Velocity is constant
• B. Magnitude of velocity is constant but the direction changes
• C. Both magnitude and direction of velocity change
• D. Velocity is directed towards the center of circle

Answer 1

Answer: (A), (C), (D)

The correct options are
A Velocity is constant
C Velocity is directed towards the center of circle
D Both magnitude and direction of velocity change

Angular speed is constant. Hence linear speed is constant i.e magnitude of velocity is constant but direction is changing.

Hence, $\left(a\right),\left(c\right),\left(d\right)$ are not true.
