Hi, I am reading through a study guide and currently going through the kinematics section. In the section on uniform acceleration it gives all the standard formulae and explains how they are derived. It says that average velocity = s/t, but also that it is equal to (v+u)/2 if the average velocity is uniform. Can someone explain this second part to me please? I understand the concept of averages and that we are dividing by 2 because we are only using 2 values, v and u. But through explaining the concept how does adding together v and u bring us the average velocity??? Thanks.
