Vectors
1. (fall06, ex1, q1, Ihas/Biswas, ch3)
When three vectors are added graphically they form a closed triangle. The largest
enclosed angle between any two of the vectors cannot

Displacement (x or y)
Distance moved from a
starting point.
Velocity (v)
How fast something is
moving (and what direction
its moving in).

Chapter 7
Chapter 7 deals with the ideas of momentum, impulse, and collisions.
Most problems relating to this chapter are actually rather simple.
Momentum
Momentum is a vector consisting of an objec

Chapter 6
Chapter 6 deals with work, kinetic energy, and potential energy.
These concepts are relatively interchangeable with kinematics, so often it is
possible to solve a problem using either meth

Chapter 3
Chapter 3 introduces the idea of vectors, relative motion, and 2-dimensional
kinematics.
Vectors
Vector: anything you can define as having both a magnitude and a direction is
known as a ve

Chapter 4
Chapter 4 deals with Newtons Laws and forces.
Force
Force measures the strength of a push or pull on an object.
Force is given in units of Newtons (N). This is an important derived unit eq

Chapter 5
Chapter 5 deals primarily with rotation. Below are a few important definitions
for this chapter.
Radians, degrees, revolutions
Youll see three different systems for measuring angle and rot

Chapter 1
Chapter 1 brings up two core issues you need to understand before really getting
started with physics 1:
1. Scientific notation
2. SI units and conversions
You can ignore a lot of stuff in

Chapter 8
Chapter 8 is a continuation of the ideas presented in chapter 5, dealing primarily
with the physics of rotating systems.
In this chapter torque () and moment of inertia (I) are the key con

Chapter 12
This chapter deals primarily with sound waves.
The most common questions relate to the Doppler Effect.
Speed of Sound
The speed of sound is not a constant. It travels at different rates d

Definition of displacement
1. (fall10, ex1, q1, Mueller/Qiu, ch2)
A particle moves along the x-axis from xi to xf. Of the following values of the initial and
final coordinates, which results in the

Stress and Strain
When an object is pulled on so as to stretch, or pushed on so as to compress, we
call the action of compressing or stretching it the stress.
Stress is defined in the same way as pr

Chapter 9.1-9.6
This chapter deals with density, pressure, buoyant force, and fluid flow.
The part about fluid flow is different enough that it deserves its own section.
Density
Density represents h

Wavelength, wave speed, wave amplitude
Wavelength is defined as the distance between two identical points on a wave.
Often we think of this as the distance between successive crests or tr

Isolation of A Lipid from Nutmeg
Introduction
The lipids isolated from most sources contain mixtures of fatty acid components.
The lipid isolated from nutmeg, however, contains almost totally the 14
