If the slope of velocity time graph is not constant at different points,then body is moving with:
Correct answer: C. Increasing acceleration
- A. Constant acceleration
- B. Average acceleration
- C. Increasing acceleration
- D. Uniform velocity
Explanation
Option C is correct.The v-t graph of an object with increasing acceleration is a parabola. . The reason why the v-t graph is a parabola is because the acceleration is proportional to the velocity. This means that the faster the object is moving, the greater the acceleration is Slope of v-t graph is acceleration. For constant acceleration,the slope of constant acceleration must be constant.For straight line,the slope is constant .

About Acceleration
Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.
