Regents Physics Dr. Marchildon, Ph.D.

Who? Students. You are responsible for your own learning. Teacher. I manage, motivate, and I make it happen; I deliver NYS Regents Physics Curriculum through classes and labs.

What? – Frayer Model for Physics

Why? Pass the NYS Regents Physics Exam. Required for some science, engineering, professional majors. Understand and appreciate the physical world, especially the very small and the very large. Make faster and smaller phones. Go to the moon or Mars.

How? Classes and Labs Teacher Fellow Students Textbook, Review Book, Reference Table Homework Handouts Links on class webpage

Physics Physics is a science that seek to explain and understand matter and energy and their interaction. Physics is a science and does utilize the scientific method. Physics is the most basic and fundamental science. Examples: electricity, motion, gravity, magnetism, waves, sound, light

Scientific Method 1.Observation (qualitative and quantitative) 2.Questioning (why? How? When?) 3. Hypothesis (explanation, educated guess) 4. Prediction based upon hypothesis (if…., then …..) 5.Experiment 6. Conclusion

Example 1.The car will not start. 2. Why won’t the car start? 3. The car will not start because the battery is dead. 4. If I replace the dead battery, then the car will start. 5. I replace the battery and then the car starts. 6. The hypothesis was correct.

Group Problem The grass is brown. Use the scientific method to explain why and how the grass is brown.

Physics is the most basic science Recall in chemistry you became familiar with atoms and parts of atoms such as protons, neutrons, and electrons. In physics we currently have The Standard Model on p. 3 of the Reference Table that says that protons and neutrons are hadrons and, as such, are made up of quarks held together by the strong force. Electrons and neutrinos are leptons and therefore lack quarks and strong force.

Proton Charge is +1 Composed of 3 quarks held together by strong force Up quark +2/3 and Up quark +2/3 and Down quark – 1/3

Neutron Zero charge Made up of three quarks held together by the strong force Up quark +2/3 and Down quark -1/3 and Down quark -1/3

Anti-particles Same mass Opposite charge Particles and Anti-particles annihilate each other with the release of energy E = mc^2
