Question

for a particle having uniform circular motion which of following is constant 1. speed 2.acceleration 3.velocity 4.displacement​

Answer 1

Answer:

1. Speed is constant.

Explanation:

This is because all other quantities i.e., acceleration, velocity and displacement are vector quantities and depend on the direction of motion. As the direction of motion is constantly changing when a body moves in a circular path, so these three are also constantly changing.

Whereas, speed is scalar and doesn't depend on the direction of the motion. So speed remains constant in a circular path.
