 Welcome to Ms. Esser and Mr. Johnson's Science 2 page.  Here you will find important information about class, as well as some helpful web sites. Important dates: Tuesday, January 16-- Midterm exam Upcoming Agenda: Study for test! SCIENCE 2  1st SEMESTER EXAM STUDY GUIDE Chapter 12—Forces  Know the parts of the equation F=mg and be able to use it to solve a problem  Pressure—what happens to pressure when force is increased or decreased?  Know the difference between forces-- gravitational, magnetic, electrical… (etc.)  Define kinetic and potential energy.  How can you tell the difference?  What is buoyancy?  How can you tell if something will sink or float?  What does that have to do with the displacement of water?  What is the Law of Conservation of Energy?  How is energy changed?  As you get farther away from the earth, what happens to your weight and mass?  Define force, friction, pressure, Newton,  weight Chapter 13—Simple Machines  Define a simple machine and name all 6 types.  What is the difference between a simple and a compound machine?  Calculate mechanical advantage using the equations MA=R/E, MA=EA/RA, MA=ED/RD  Calculate work using W=Fd  What is effort force and resistance force?  What is effort distance and resistance distance?  What is effort arm and resistance arm?  What are the 3 types of levers?  What is efficiency, work input, and work output?  Define mechanical advantage, gears, pulleys, levers, etc… Chapter 14—Motion  Define Newton’s 3 laws of motion and give an example of each.  What is centripetal force and centripetal acceleration?  What is the difference?  Define inertia, joule, speed, velocity  Calculate speed using v=d/t  Calculate force using F=ma  What are action and reaction forces?  Give examples.  What are balanced and unbalanced forces?  Give examples.  Describe weightlessness and when it occurs.  Calculate acceleration using a=vt  Use a graph to calculate average speed Chapter 18—Sound  Calculate overtones and fundamental frequencies  How does temperature affect the speed of sound waves?  What are reverberations and what causes them?  What is constructive and destructive interference?  What are compressional and transverse waves?  What is pitch?  What kind of strings on a guitar would produce high pitch?  Low pitch?  What is diffraction?  Give an example.  What is a wavelength and how do you measure it?  What kind of sounds can break glass?  Define frequency, intensity, Doppler effect, acoustics, harmony, quality, wave. Chapter 19—Light  What is the electromagnetic spectrum?  What are its parts?  What are their wavelengths and frequencies (relative to each other)?  What is the photoelectric effect and what produces it?  What kinds of rays produce tanning?  What is interference and what kinds of patterns can it produce?  What is reflection and refraction of light?  What are the primary colors of light?  What is produced when they are mixed?  What are filters?  What happens to the color of objects when viewed through a filter?  What does a polarizing filter do to light?  What are transparent, translucent, and opaque objects?  Why does light separate into different colors when going through a prism?  Define index of refraction, photocell, radiant energy, polarization, wave nature of light. Chapter 16—Electricity What are conductors and insulators?  Give examples. What are the parts of a simple circuit? Calculate resistance using R=V/I What is the difference between series and parallel circuits? Define circuit, resistance, and grounding. What are wet cells and dry cells?
