प्रश्न
Which of the following quantity remains constant in uniform circular motion:
पर्याय
Velocity
Speed
Acceleration
Both velocity and speed

उत्तर
Speed
Speed is scalar but velocity and acceleration are vector quantities. So, speed remains constant but velocity and acceleration change with the change in direction, and in the circular motion the direction of motion changes at every point.
