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.

Which graph represents the motion of a car that is traveling along a straight road with a uniformly increasing speed?
If an object is moving with constant velocity of 20ms-1 towards north, then its acceleration will be:
how long would it take a car starting from the rest and accelerating uniformly in a straight line at 5 m/sec square to cover a distance of 200 m?
An object falls freely from rest. The total distance covered by it in 2 s will be(Note: The acceleration due to gravity 'g' is 9.8 m/s2.)

If the slope of a velocity-time graph gradually increases, then the body is said to be moving with
