Physics is the science that studies the nature and properties of matter and its motion through space and time. It seeks to understand the interactions between objects, from subatomic particles to galactic structures. The language of physics is mathematics - physical laws take the form of precise equations that can be used to make predictions. Physics is divided into main branches that study different phenomena like motion, electricity, light, heat, and modern areas like relativity and quantum mechanics.

1. Introduction to Physics Unit 1 Class 1 E. Alexander Burt Potomac School

2. What is Physics? Start with the root of the word: Physics – physical – think bodies. Not human bodies! Bodies in the old sense of the word – think objects.

3. Objects of all sizes – from subatomic particles all the way up to galactic superclusters! So physics is the science of the nature and interaction of objects. What are the objects like?

4. What happens when multiple objects “interact” Could be collisions

5. Could be other forces.

6. An analogy to sports Suppose you're watching a sport that you have never seen before: The book uses a baseball analogy

7. My own experience is Lacrosse As you watch, some things are “legal moves” and some are not. So you develop a “theory” about what's a legal move.

8. And you confirm or change your theory by watching more moves.
