About this unit
How high can you jump on that trampoline? Sure, you could just start hopping around, but physics gives us a safer option. Use your knowledge of energy, you can mathematically model energy of an object or system, such as a spring, to predict how systems will behave.
Push down on a spring until you can't anymore; how much energy is stored in there?
If energy can't be destroyed, then how come I'm so tired all the time?
