If you’re not studying physics, there’s a good chance that the differences between velocity and acceleration are lost on you – even if you drive a car or deal with them regularly. The term “velocity” refers to an object’s speed in a certain direction, whereas acceleration is the rate of change of that velocity with respect to time. See what else you can tell us about the two in this quiz!
