Every single one of us in the classroom at some point has or will use the electric stairs inside John Jay College. Now that I am taking physics and learning new concepts I have realized the electric stairs travel at a constant speed because all parts of the stairs move simultaneously. However, many would say the electric stairs move at a constant velocity, but in reality this is not true. Even though the speed remains the same, the direction of the electric stairs changes, therefor it is incorrect to say it has a constant velocity because there is a change in direction.
