You will have your physics final towards the end of May. It will cover EVERYTHING that you have learned during PHYSICS!
YOU NEED:
1. Bring a calculator to class everyday
2. Bring your new folder to class tomorrow (See the assignment titled: "Intro to Physics")
STUDY GUIDE FOR FINAL!
FOR ALL KEY TERMS YOU MUST KNOW THE DEFINITION AND AN EXAMPLE. EMAIL ME WITH ANY QUESTIONS!!!!!!!
CHAPTER 1 SECTION 1
KEY TERMS: Motion, Reference Point, International System of Units, Meter, Speed, Velocity,
Average Speed, Constant Speed
FORMULAS: Remember the triangle.
Speed = Distance/Time Distance = Speed X Time
Time = Distance / Speed
Average Speed = Total Distance/Total Time
CHAPTER 1 SECTION 2
Key Terms: Pangaea, plate, plate tectonics, boundary, Convergent boundary, Divergent
boundary, Transform boundary, Geologist
Formulas: None
CHAPTER 2 SECTION 1
Key Terms: Force, Net Force, Unbalanced Forces, Balanced Forces, Inertia, Mass, Newton's
First Law of Motion, Contact Forces, Action at a Distance Forces", Applied Force,
Gravity Force, Normal Force, Friction Force, Air Resistance Force, Tension Force,
Spring Force, Strong Forces, Vectors, Magnitude, Centripetal Force
Formulas: NONE
CHAPTER 2 SECTION 2
Key Terms: Newton, Newtons Second Law, Force,
how does mass and acceleration change the force, mass,
Formulas: Force = mass X Acceleration (think of the triangle)
Acceleration = Force / Mass
CHAPTER 2 SECTION 3
Key Terms: friction, sliding friction, rolling friction, fluid friction, gravity, free fall, projectile,
air resistance, terminal velocity, weight
Formulas: Weight = Mass X Acceleration due to gravity
CHAPTER 2 SECTION 4
Key Terms: momentum, law of conservation of momentum, Newton's Third Law of Motion
Formulas: Momentum = Mass X Velocity
p = m X V
CHAPTER 4 SECTION 1
Key Terms: work, Joule, How do you know work is being done on an object?
Formulas: Work = Force X Distance
work is measured in Joules
CHAPTER 5 SECTION 1
Key Terms: Work, Joule, Energy, kinetic energy, potential energy, elastic potential energy,
gravitational potential energy, mechanical energy, thermal energy, chemical energy, electrical energy,
electromagnetic energy, nuclear energy, erg
Formulas: Kinetic Energy = Mass X (Velocity)^2 / 2
Gravitational Potential Energy = Weight(of object) X Height
Gravitational Potential Energy = Mass X Acceleration due to gravity X Height
Unit for energy = J
