Question

in velocity time graph, velocity is proportional to time,it has

A) increasing acceleration
B) decreasing acceleration
C) zero acceleration
D)none of these


plss explain ...​

Answer 1

In velocity time graph, velocity is proportional to time, it means that when time will increase velocity will also increase.

So, the correct option will be

A) Increasing acceleration

Basically the body can be in uniform acceleration(when velocity is increasing uniformly) or increasing acceleration(when velocity is increasing non uniformly)

Well it can have both decreasing acceleration too, if we take the meaning of proportional as inversely proportional.

Answer 2

Answer:

If the object's velocity increases over time, its acceleration increases as well, hence A is the right answer.

Explanation: 

Acceleration is the rate of change of velocity, When velocity varies, there is acceleration. When an object's velocity, i.e. its speed or direction, changes, it is said to be accelerating. Velocity / Time = Acceleration

Acceleration is indicated in a velocity-time graph by the slope, or angle of inclination, of the graph line.

If the slope of the line is upward, the acceleration is positive.

If the line is horizontal, the velocity is constant.

When the line slopes downhill, velocity decreases and acceleration decreases.
