Question

The slope of velocity-time graph for motion with uniform velocity is equal to
A. final velocity
B. initial velocity
C. zero
D. none of the above

Answer 1

Hint: We should know that the velocity-time graph is used to describe the motion of the objects which are moving in a straight line. The graph can be used to show acceleration and to work out displacement. Once we know the purpose of the velocity-time graph, we can find out the answer to the required question.

Complete step by step answer:
 As asked in the question, the slope of the velocity-time graph gives acceleration. When a body moves with constant velocity, then acceleration will be zero. So, the slope of the velocity-time graph will be zero.
Therefore, we can say that the correct answer to the question asking about the slope of the velocity-time graph for motion with uniform velocity is equal to zero.
So, among the mentioned options, the correct one is Option C.
We can say that for a body when it is moving with uniform velocity, it experiences zero acceleration. So, in the velocity-time graph, the time axis will be zero throughout. Ultimately, we will get a straight line which will be parallel to the time axis.
Note: There are a few points that are required to be known by us regarding the velocity-time graph. Here they are mentioned below:
1. The slope of the velocity-time graph always gives us an idea about the acceleration of the particle.
2. The area under the velocity-time graph will give us an idea about the displacement of a particle.
3. The instantaneous value of the velocity of the particle at different points of time can also be found using the velocity-time graph.
