Q: When an object is moving at the same speed, what will be its acceleration?
  • A. negative
  • B. positive
  • C. zero
  • D. variable
Correct Answer: Option C - The rate of change in velocity of an object is called acceleration. Its unit is meters per second², and it is a vector quantity. When an object is moving at the same speed, its acceleration is always zero, because the speed of the object remains constant relative to time.
