5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...
