Elementary Energy Complete Series

In our Elementary Energy Complete Series (4 Titles) we find our animated caveman, Zog, pondering basic questions about energy as understood from a scientific viewpoint: where energy comes from, what forms it can take, how it can be changed, and how it is used.KINETIC AND POTENTIAL ENERGY introduces Zog to energy of movement and stored energy. Working with inclined planes, springs and a bouncing ball he learns about both kinds of energy and how each kind of energy can be changed into the other. Also, he learns how chemical potential energy is used to create heat, mechanical power, light and electricity.GRAVITY, FORCE and WORK introduces Zog to Newton’s basic laws of motion. By observing objects on earth and in space, Zog learns that nothing can start moving, speed up, slow down, change direction or stop unless a FORCE is applied to it – even if the force is hard to see, like GRAVITY or FRICTION. He learns that for every force there is an equal and opposite force and that is the principl
