2. We can only add and subtract numbers in Physics if they have the same units. For example I can add 5.0m to 12m to get 17m but I cannot add 5.0m to 10m/s. You cannot add a velocity (10m/s) to a distance (5m) and get anything meaningful. Use dimensional analysis to ensure that the kinematic equations shown below adhere to this rule. (Note: it does not matter at this stage if you understand the physics behind the equations). The units for each variable are given. The first one is done for you. Variable Units d m m/s m/s a m/s S
