Post #5 - Acceleration

Today we did a lab about acceleration. Acceleration means the change in velocity per unit in time (m/s^2). Acceleration is also the change in velocity and direction. In graphs, you can tell if the graph represents acceleration if the graph is a curved dt graph. In our lab, we used a danger board and a skateboard to go down the hill. The skateboard went down the hill faster than the danger board. On the graph the graph showed as exponential. We could also see a little bump in the line because the hill was not perfectly consistent. Acceleration is the slope of a velocity vs. time graph. Since the graph is exponential the danger board and the skateboard picked up speed as it went down the hill. This is because the velocity vs. time graphs slope increase as time went on. The lab was really fun.
