equations of motion v = v0 + at s = s0 + v0t + ½at2 v2 = v02 + 2a(s − s0 Kinematic equations relate the variables of motion to one another. Each equation contains four variables. The variables include acceleration (a), time (t), displacement (d), final velocity (vf), and initial velocity (vi). If values of three variables are known, then the others can be calculated using the equations. This page describes how this can be done In higher level physics, you'll see a few other extensions of this technique: the use of symmetry to reduce the number of equations you have to consider, the separation of variables technique, and the eigenfunction expansion technique (you can treat each eigenfunction as if it were a separate dimension) Solve the equations.
