I mean to do this post last week but i forgot. For this post i decided to talk about acceleration. Acceleration is the change in velocity per unit of time. I choose a picture of me and my friend playing on the beach. In this picture he is accelerating faster than I am and i'm unable to catch him. He is increasing his speed at a constant rate while mine is staying the same. This means i have an acceleration of 0. Constant speed is zero acceleration because acceleration only counts the change of speed. Another good example is gravity which accelerates at 9.8 m/s.
