Unit Paragraphs

Paper coming out of a Printer: Constant Velocity

Velocity is speed and direction. A constant velocity consists of same speed and direction. In this picture, the paper is exiting the machine at a constant velocity. We are not taking into account the time during which the paper goes from 0 m/s to exiting velocity. On a position time graph, the line would be first quadrant going at a constant speed and forward direction. On a velocity time graph, the line would be horizontal in the first quadrant.

Pushing a Glass:  Acceleration

Acceleration is the rate of change of velocity. The object could be speeding up or slowing down to represent acceleration. In the old Western movies, there is a bartender who launches a full glass of beer to someone at the other end of the bar. The beer glass accelerates from 0 m/s/s to a maximum velocity. Then the beer glass accelerates again slowing down as it comes closer to persons hand. The glass’s velocity is positive, and its acceleration is negative; causing the glass to slow down. On a position time graph, the line would be in the first quadrant going in a negative direction slowly coming to a rest. On a velocity time graph, the line is in the first quadrant starting with a high velocity and slowing down to a rest
