Here are some Q.&A. for a science book: Matter and Energy.

Here they are:

2. State the law of conservation of energy: Energy may change forms, but it can neither be created or destroyed. 
3. Which two scientists are most often named for discovering this law of conservation of energy?:English scientist J.P. Joules and German scientist Hermann von Helmholtz.
4. What is kinetic energy?: Energy of motion.
5. What does the word thermodynamics mean? The study of heat-motion. Thermo- means heat, and dynamics is the study of motion.  

      6.  What is the metric unit used to measure work called and why?: The Joule, because he did so much    work in the study of energy.  


That's all for now!
