Question

What would be the shape of
а
speed-time graph of a body
moving
with variable speed?​

Answer 1

Answer:

The slope will not be parallel to the time axis as its speed is not constant and so it will not have any specific shape

Answer 2

Explanation:

If the speed is increasing uniformly with time then its graph is a straight diagonal line slanting up from left to right.

If the speed is decreasing uniformly with time then its graph is a straight diagonal line slanting down from left to right.

If the speed is increasing uniformly with time then decreasing uniformly with time then its graph will resemble a tooth of a saw.

If the acceleration is increasing uniformly with time then its graph is a parabola pointing up from left to right.
