When velocity time graph is a straight line parallel to time axis then:
Correct answer: B. Acceleration is zero
- A. Acceleration is constant
- B. Acceleration is zero
- C. Acceleration is variable
- D. Velocity is zero
Explanation
The correct answer is that the acceleration is zero. This is because a straight line parallel to the time axis on a velocity-time graph indicates no change in velocity over time, resulting in zero acceleration. Option A is incorrect because constant acceleration would produce a line with a slope, not parallel to the time axis. Option C is incorrect as variable acceleration would create a curve, not a straight line. Option D is incorrect because a straight line parallel to the time axis indicates constant velocity, which could be any value, not necessarily zero.

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.
