WebAcceleration is a change in velocity, either in its magnitude —i.e., speed—or in its direction, or both. In uniform circular motion, the direction of the velocity changes constantly, so there is always an associated acceleration, even though the speed might be constant. WebJan 25, 2024 · Acceleration is the rate of change of speed: a = d v d t. As long as it is positive, the change of speed is positive. Taking the foot slowly off the accelerator pedal means that d a d t < 0, but if we pretend the wind and friction are absent, you will eventually end up with a = 0 (this is just how cars work, you need to use brakes to get a < 0 ...
