3 equations of Motion There are three equations of motion that we use. I will derive 1& Though you will not need to derive these, these illustrate a very important practice we undertake in Physics. There are situations where we can combine multiple equations in order solve problems that don’t seem to have a solution. 1 is created by combining a=Δv/Δt & Δv=v-v 0 2 can be found by graphing the motion of an accelerating object on a v vs t graph and finding its area. It can be derived using calculus. 3 is created by combining equations 1&2
