Electrical Energy
A bolt of lightening is electrical energy. This is the same kind energy used by an electrical outlet. Electrical energy travels through power lines and then helps make lots of different machines work.
Motion Energy:
Moving things have energy. The faster something is moving, the more energy it has. Pose this question to your students: Which do you think has more motion energy, a book that is falling off a table or a truck driving down the road at 60 miles per hour? You can explain that the truck has more motion energy because it is traveling much faster than a book. Another reason why the truck has more motion energy is that the truck is much heavier than the book.
