Q: Change in velocity / time taken =
  • A. impulse
  • B. speed
  • C. acceleration
  • D. displacement
Correct Answer: Option C - Acceleration is the rate of change in velocity of a body. This is a vector quantity. Its unit is meter per second square i.e m / sec². Its dimensional formula is [LT⁻²]. Acceleration = change in velocity/time
