... Acceleration is the change in velocity and is measured in m/s2 or ft/s2. It is a vector and is used for any change in velocity – speeding up, slowing down, or turning). Whenever you observe that the velocity of an object is not constant, an acceleration is acting. The problems we will consider alway ...
