Answer:

Speed and Velocity are different in uniform circular motion.

Explanation:

Speed and Velocity are different in uniform circular motion due speed a scalar quantity but in velocity is a vector quantity, in a circular motion every instend of time velocity is chage.

Speed and velocity in uniform circular motion are respectively CONSTANT AND VARIABLE.

  • In a uniform circular motion an object travels in a circular trajectory with a constant speed.

  • However, since velocity is a vector we can say that the magnitude of velocity remains constant but its direction changes, hence the velocity is variable.

  • At every point on the circular trajectory the direction of velocity vector is tangential to the trajectory. So, the direction changes with time.

  • In the diagram, you can see initial velocity "v_(i)" and final velocity "v_(f)". The directions are different.

Hope It Helps.
