If slope of velocity time graph is not constant at different points then body is moving with:
Correct answer: B. changing acceleration
- A. Uniform velocity
- B. changing acceleration
- C. Average acceleration
- D. Constant acceleration
Explanation
Since the slope of the velocity time graph represents the acceleration of the body, hence a changing slope of the graph means that the acceleration is also changing.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
