This week in physics we are learning about work and energy.  The major concept that I had to grasp was that energy is always conserved.  No matter what the case PE will always equal KE or PEs.  This has helped me with my take home quiz because you need to know this concept in order to solve the problems.  We also are learning about the springs and the spring constant.  Although since we don't live in a perfect world energy is not always conserved.  Since there is air friction an object's energy isn't always conserved.
