If the acceleration of a body is zero then the slope of its v-t graph:
Correct answer: A. parallel to time axis
- A. parallel to time axis
- B. perpendicular to time axis
- C. Straight line from the origin
- D. Straight line inclined to the time axis at an angle of 45o
Explanation
The slope of a velocity-time (v-t) graph represents acceleration. If the acceleration of a body is zero, it means the velocity is constant, leading to a horizontal line on the graph, parallel to the time axis. Option A is correct as it correctly describes this scenario. Option B is incorrect because a line perpendicular to the time axis is not possible in this context. Option C and Option D both describe scenarios where there is a change in velocity, indicating the presence of acceleration, which contradicts the condition of zero acceleration.

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.
