When the velocity time graph is a straight line parallel to time axis then:
Correct answer: C. Acceleration is zero
- A. Acceleration is constant
- B. Acceleration is variable
- C. Acceleration is zero
- D. Velocity is zero
Explanation
A velocity-time graph that forms a straight line parallel to the time axis implies a specific behavior in terms of acceleration. When the velocity-time graph is a straight line parallel to the time axis, it indicates that the object's velocity is constant over time. In this scenario, as velocity remains constant, the acceleration becomes zero because there is no change in velocity over time.

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.
