Question

A body moving along a straight line with uniform speed is an example of a body having:

• A. uniform velocity
• B. variable velocity.
• C. variable speed
• D. None of these

Answer 1

The correct option is A

uniform velocity

Explanation for correct answer: Option(A)

1. When an object covers equal displacement in equal interval of time then, object is said to be in uniform velocity.
2. Here in this case, body is moving along a straight line with uniform speed, so its velocity will also be uniform since, direction is not also changing.

Hence, A body moving along a straight line with uniform speed is an example of a body having: uniform velocity

Explanation for incorrect answer(s):

Option(B): variable velocity: When an object changes its direction or its covers unequal displacement in equal time interval.

Option(C): variable speed: When an object covers unequal distance in equal time interval.
