Question

+2) A particle is moving in a horizontal circle with constant speed. It has constant
(1) Velocity
(2)Acceleration (3) Kinetic energy (4)D
​

Answer 1

velocity

Explanation:

it has constant velocity. there is a difference between velocity and speed. velocity is a vector quantity as it has magnitude as well as direction whereas speed is a scaler quantity as it has only magnitude not direction.

so the particle is moving with constant velocity as it has magnitude as well as direction.
