Rate of change of velocity is called what?
Correct Answer:
Acceleration
Explanation:
Acceleration is the rate at which velocity changes with time. Since velocity includes speed and direction, any change in either—speeding up, slowing down, or turning—constitutes acceleration. Positive acceleration means speeding up in the same direction as the motion; negative acceleration (deceleration) means slowing down or changing direction opposite to the motion. If velocity doesn’t change, acceleration is zero. Mass and displacement aren’t about how velocity changes: mass is a property of matter, and displacement is the straight‑line change in position. So acceleration is the correct term.
