Question

14. A particle moves with uniform velocity which of the following statements about the motion of the particle is
true?
1) Its speed is zero
2) its acceleration is zero
3) Its acceleration is opposite to the velocity 4) Its speed may be variable

Answer 1

Answer:

2.) Acceleration is 0

Explanation:

Uniform velocity:

Velocity is a vector which includes both speed and the direction of motion.

Velocity can thus change with change in speed or direction.

But it is given that the velocity is uniform that means it does not change

it can happen only when the speed and direction both are unchanged.

(:. option 4) is wrong)

no change in velocity means acceleration is 0.

so option 3) is wrong and option 2) is correct.

now, option 1) is not always true. It is not guarantee that it's speed will be 0. it can have speed 100 km/h also.

so the answer is 2).

i hope it helped!!!! follow!
