Physics (Period 2/3)
Course Description
Physics is about the nature of basic things such as motion, forces, energy, matter, heat, sound, light, and the composition of atoms.
Physics is the study of the fundamental laws of nature. Physicists want to know how things work. They observe nature and figure out the rules or laws that govern its operations.
Creativity plays an important role in interpreting nature, and in finding ways to solve problems. Physics helps develop creative, logical, and consistent ways of thinking. Because of these attributes, people who study physics go on to careers in many interesting fields.

This short video from PBS Learning Media features a team of engineers who recreate a medieval trebuchet
using only technologies available in the Middle Ages. It does a good job of exploring the advantage of the offcenter
pivot and the purpose of the heavy counterweight (which revolutionized catapult-type projectile warfare).
