Acceleration refers to the rate of change of velocity - how quickly velocity changes. In symbols: dv/dt. When the velocity changes, the speed may, or may not, change. For example, if an object moves in a circle at a uniform speed, its velocity is changing, but its speed is not.

Acceleration is the rate of change of velocity with respect to time. Speed is the magnitude of velocity, while velocity includes both the speed and direction of motion. Therefore, when an object is accelerating, both its speed and/or its direction can be changing.
The derivative of velocity is acceleration. Acceleration measures how quickly an object's velocity is changing over time. It shows how much the speed or direction of an object is changing at any given moment.
Acceleration is the rate at which an object's velocity changes over time. It measures how quickly an object's speed or direction changes. When an object accelerates, its velocity increases or decreases, depending on the direction of the acceleration.
Speed and velocity both involve the rate of motion, with velocity additionally considering direction. Acceleration involves changes in velocity over time, indicating how quickly an object is speeding up or slowing down. Speed and velocity relate to the rate of motion, while acceleration represents changes in velocity over time.
Acceleration is the rate of change of velocity over time. It measures how quickly an object's velocity is changing. Speed is the rate at which an object covers distance, whereas velocity includes both speed and direction.
A constant speed has no acceleration. When an object is moving at a constant speed, its velocity remains the same over time, and there is no change in acceleration.
