Question

Draw velocity time grap for the following situation: 1) when a body moving with uniform velocity. 2) when a body is moving with variable velocity but uniform acceleration. 3) when a body is moving with a variable velocity but non uniform retardation. 4) when body is moving with a variable velocity and variable acceleration.

Answer 1

1)When a body is moving with constant velocity then, there will be a straight horizontal line but not from 0 velocity.
2)When the body is accelerating uniformly, there will be a straight line with positive gradient.
4)The above diagram should answer your question no 4
I'm not too sure about 3 so I'll skip it. Sorry.
