We finished the transport section with a look at Work, Potential & Kinetic energy. Those of you aiming for Credit need to carry out calculations involving kinetic energy using
E_k = \displaystyle {1 \over 2}mv^2
Here is a video about work, potential energy & kinetic energy from Bozeman Science

Most of the calculations will be based on the principle of conservation of energy. Dr. Altman has an excellent series of videos examining conservation of energy examples from Roadrunner cartoons.
