AP Physics Intro 2013

What is Physics? (Page 1) The main objective of science (physics) is to identify a limited (small) number of fundamental laws (relationships) that govern natural phenomena and use them to predict the results of future experiments. Fewer Relationships-- Better Predictions The beauty of physics lies in the simplicity

What is Physics (cont) Classical mechanics- motion, force, energy Relativity- heavy objects at light speed Thermodynamics- heat, work, temperature Electricity and Magnetism Optics- electromagnetic waves Quantum Mechanics- behavior of subatomic particles Classical Physics - before 1900 Modern Physics - after 1900

Why should I take Physics Physics is the most fundamental of all the natural sciences. Physics is the most mathematical and experimental of the sciences All the other sciences are based on the concepts and methods of physics. Foundation of all sciences, engineering, technology. Best way to learn math

Why take Physics in High School Tends to be easier Classes are smaller o 20 versus 200 Teachers are here to teach o College teachers are there to do research HS teachers speak English as their first language Tuition is cheaper

Why is Physics Hard? Mathematical - precise, close isn’t good enough. Experimental- requires rigor and care “Magic” world of physics o Simplifying assumptions Not common sense

How should I study Physics Read the text, listen in class, take notes For each new concept learn o Definition, symbol, unit Work problems including example problems o Copy the steps, complete any missing steps, compute each step with your calculator Don’t get behind o Isaiah 28:10 “For it is precept upon precept, precept upon precept, line upon line, line upon line, here a little, there a little. o We are building a brick wall, not baking a cake Textbook recommends 2 hrs study for each 1hr of class.

Tips for Working Problems You don’t know anything until you have practiced. Do not deceive yourself into thinking you understand a problem merely because you have seen it worked on the board. Your ability to “read” (interpret) a problem is the key to solving the problem. o Given o Asked o Formula Use the correct symbols and the correct units
