Question

For the given acceleration-time graph, choose the correct option:

• A. Body is in uniform motion.
• B. Velocity increases linearly with time.
• C. Force acting on particle is zero.
• D. Variable force is acting on the body.

Answer 1

Answer: (D)

Variable force is acting on the body.

Since acceleration is not constant, variable force is acting on the body. Correspondingly, force is non-zero, body is not in uniform motion and velocity-time graph is not a straight line.
