Question

For a particle having a uniform circular motion, which of the following is constant
A Speed (B) Acceleration
(C) Velocity (D) Displacement​

Answer 1

Answer:

(A) Speed

Explanation:

Speed is a scalar quantity while all others are vector quantities. Scalar quantities do not have direction. They only have magnitude. Vector quantities have both magnitude and direction. In a uniform circular motion, the direction changes at every point of the circle. So, in a uniform circular motion, vector quantities cannot be constant.

Also, if the motion is uniform, the speed is always constant as the object will cover equal distance in equal intervals of time.

Speed is also a scalar quantity. So, out of these options, the correct answer is (A) Speed

Answer 2

Answer:

The answer is A. Speed.

Explanation:

Speed exists as a scalar quantity while all others are vector quantities.

Speed exists as a scalar quantity that indicates "how quickly an object is moving." Speed can be thought of as the rate at which an object covers distance. A fast-moving object contains an increased speed and covers a relatively large distance in a short amount of time.

For a particle containing a uniform circular motion, A. speed stands constant.
