Concept of The Day #7

Scientists have two different measurements for how fast objects travel. Speed is how far an object moves in a certain time. Velocity is speed in one direction, so it changes every time the speed of direction changes. On a roller coaster, your speed is constant ( you travel the length of the ride in a set amount of time ), but your velocity keeps changing as you point in different directions.
