Question

the velocity time graph of a particle is not a straight line its acceleration a)zero b)constant c)negative d)variable

Answer 1

Answer: According to me option D is right answer

Answer 2

Answer:

If the velocity-time graph of a particle is not a straight line, then the acceleration of the particle is variable.

Explanation:

The velocity-time graph shows the relationship between the velocity of a particle and the time it takes to reach that velocity. A straight line on this graph would indicate that the acceleration is constant, meaning the rate of change of velocity is the same at all times. A non-straight line, on the other hand, indicates that the acceleration is changing, meaning the rate of change of velocity is not constant. Therefore, the acceleration is variable.

It's important to note that a non-straight line can be a curve, which means that the velocity is changing at an increasing or decreasing rate. So if the curve is increasing the acceleration is positive, and if the curve is decreasing the acceleration is negative.
