Question

When a particle moves in a circle with a uniform speed

  • its velocity and acceleration are both constant

  • its velocity is constant but the acceleration changes

  • its acceleration is constant but the velocity changes

  • its velocity and acceleration both change.

Solution

 its velocity and acceleration both change.

In a circular motion, the direction of particle changes. Therefore, velocity, being a vector quantity, also changes.
As the velocity changes, acceleration also changes.

  Is there an error in this question or solution?
