Question

Draw the velocity-time graph for

a) Uniform motion

b) Uniformly accelerated motion

c) Uniformly retarded motion

​

Answer 1

a) During uniform motion the acceleration of the body is 0 therefore the velocity time graph for a uniform motion is a graph line parallel to the time axis where slope (i.e acceleration) = 0

b) During uniformly accelerated motion the graph is a straight line passing through the origin with a constant slope. 

c) During uniformly retarded motion the graph is a straight line downwards which shows decreasing velocity at a uniform rate.

Answer 2

Answer:

Hii mate this helps u to draw

For a uniformly retarded motion, retardation( and hence acceleration) is a non-zero constant. Since slope of velocity-time graph is equal to acceleration, it can be concluded that slope of velocity-time graph is a non-zero constant. Hence, the velocity-time graph is a straight line inclined to the time axis.
