This topic is in the 'Motion Problems with Constant Velocity' section. In this section you'll see tutorials that help define a lot of words that come up in motion problems, like distance, displacement, speed, and velocity. You'll learn to tell speed and velocity apart, and also see some tricks related to average speed and velocity. In addition, you'll become an expert with the distance equals speed times time equation, which is one of the most useful equations you'll ever learn!
