Which quantity is defined as a measure of the rate of change of speed over the time taken?

Explanation:
Acceleration is the quantity that tells you how quickly an object's velocity changes with time. Since velocity includes both speed and direction, acceleration describes how fast the speed is changing (and also accounts for any change in direction). In other words, it measures the rate of change of velocity per second. For example, if a car speeds up from 0 to 20 m/s in 4 seconds, its acceleration is 5 m/s². Velocity describes how fast and in what direction an object is moving, displacement is the overall change in position, and momentum depends on mass and velocity but does not convey how quickly those values are changing.
