6. Advice for Success  Reading text  SMALL DOSES  Intro, Summary, & Vocabulary  KEEP PACE WITH THE CLASS  Read your notes EACH NIGHT, ask question next day  Study with a friend

7. Definition of Physics  Physical Science that deals with the various forms of energy.  It examines how one form of energy can be transformed into another.

8. Physics  The goal of physics is to use a small number of basic concepts, equations, and assumptions to describe the physical world.  These physics principles can then be used to make predictions about a broad range of phenomena.

9. Major Areas in Physics  Mechanics  Thermodynamics ( Fluids and Heat)  Wave motion & Sound  Optics  Electricity & Magnetism  Relativity  Quantum Mechanics

10.  There is no single procedure that scientists follow in their work. However, there are certain steps common to all good scientific investigations.  These steps are called the scientific method. Scientific Method

11. Models  Physics uses models that describe phenomena.  A model is a pattern, plan, representation, or description designed to show the structure or workings of an object, system, or concept.  A set of particles or interacting components considered to be a distinct physical entity for the purpose of study is called a system.

12. Hypotheses  Models help scientists develop hypotheses.  A hypothesis is an explanation that is based on prior scientific research or observations and that can be tested.  The process of simplifying and modeling a situation can help you determine the relevant variables and identify a hypothesis for testing.

13. Controlled Experiments  A hypothesis must be tested in a controlled experiment.  A controlled experiment tests only one factor at a time by using a comparison of a control group with an experimental group.

14. Definition of Matter  Anything that has weight and takes up space.  Any solid, liquid, and gas.  Anything that has mass and inertia.

15. Definition of Mass  A measure of the quantity of matter in an object.  Mass is NOT the same as weight, which is a force that depends upon gravity.

16. Definition of Inertia  A property of matter that opposes any change in its state of motion (A body in motion remains in motion. A body at rest remains at rest.).  Greater Mass = Greater Inertia

17. Inertia Balance  Relationship between periodic motion and mass.

18. Definition of Density (Mass Density)

19. Definition of Energy  The capacity to do work.  Work means to move something.  Energy is the concept that unifies physics.

20. Potential Energy  Stored energy or energy due to position.

21. Kinetic Energy  Energy of Motion

22. Conservation of Energy  The total amount of energy in a given situation is constant.  Heat is a dissipative form of energy.

23. Matter and Energy  Albert Einstein (1905) finds a relationship between matter & energy.

24. Matter and Energy  Since “c” is a constant:  As E increases, m increases  Energy & mass can be thought of as two forms of same thing.  Matter = Concentrated Energy
