Question

explain how to find the distance travelled by a body moving with uniform motion from graph

Answer 1

1) Velocity-time graph when body is at rest :By saying that a body is rest, it means that the velocity (v) of the body is zero at time (t). So, the velocity-time graph of a body at rest is a straight line​ on the time axis, as shown below:
2) Velocity-time graph when body is in uniform motion: By saying that the body is in uniform motion or the velocity of body is uniform, it means that the velocity of the body does not change with time and hence there is no acceleration. So, the velocity-time graph of a body moving with uniform velocity is a straight line parallel to the time axis, as shown below:

3) Velocity-time graph of uniformly accelerated motion: When a body moves with uniform acceleration, its velocity changes by equal amounts in equal intervals of time. So, the ​velocity-time graph of a body moving with uniform acceleration is a straight line inclined to the time axis, as shown below:
4) Velocity-time graph non-uniformly accelerated motion: A body is said to have a non-uniform acceleration if its velocity changes in an irregular manner. So, the ​velocity-time graph of a body moving with non-uniform acceleration is a curve line inclined to the time axis, as shown below:​
