Quantitative properties - associated with numbers Units must always be specified Scientific measurements use the metric system SI Units Seven base units are used by SI Prefixes are used to modify powers of 10 of these units Length and Mass Mass - the measure of the amount of material in an object Temperature - a measure of hotness and coldness (physical property) Heat flows spontaneously from the hotter object to the colder one Celsius scale - created considering water's boiling and freezing points Kelvin scale - created so that 0K is the lowest possible attainable zero (absolute zero) The Kelvin and Celsius scales use the same-sized units around a different zero Derived SI Units - obtained by the multiplication or division of one or more base units

Work

Newton?s Laws Sir Isaac Newton Newton?s First Law Gravity Force This picture demonstrates Newton?s first law as it shows an object at rest. The reason it is at rest however, is because there are balanced forces at work. The gravity is pulling the rocket down, but that force is counter-acted by the equal force created by the base, and therefore the ground on which the rocket sits. Obviously, there are other forces at work stopping the rocket from tipping over when pushed by things such as wind, such as the red tower.

Gas Laws -study the relationships that exist between pressure, volume, temperature and amount (moles) of gas. Boyle?s Law Pressure-volume relationship At constant temperature and amount, the pressure and volume of a gas are inversely proportional. As pressure increases, volume decreases. P1V1=P2V2 Charles? Law Temperature-volume relationship At constant pressure and amount, the temperature and volume of a gas are directly proportional. V1/T1=V2/T2 Gay Lussac?s Law Pressure-temperature relationship Under conditions of constant volume and amount, the temperature and pressure of a gas are directly proportional. P1/T1=P2/T2

Work and Power Scientific Work Energy can be transferred into or out of a system by work Work: a measure of energy transferred into or out of a system by a force (F) acting over a distance(d) Work needs 3 key ingredients: force, displacement, and cause Work is only done when force acts upon an object to cause a displacement of the object Work is only done when components of a force are parallel to the object?s displacement Examples: a teacher applying a force to a wall becomes exhausted NOT WORK no displacement A book falls off a table and free falls to the ground NOT WORK no force to cause displacement a rocket accelerates through space WORK A force causes a displacement

Conversions Regarding the Metric System and some Associated Formulas By Toomuchswag Sources: My Chemistry Notes and http://www.simetric.co.uk/siprefix.htm for some verification Most of the world besides the United States uses the metric system, a much simpler measuring tool according to many. The Metric system works in powers of ten: The prefixes work like this: Kilo Hecto Deca R (this is the regular unit, be it meters, grams, etc. we have given it the letter R) Deci Centi Milli Some important formulas: Density: Mass/Volume 1calorie or cal is the amount of energy required to raise the temperature of water by 1 degree Celsius

the amplitude of a wave is the wave's height from zero to the crest. the wavelength is the distance between the crests. the frequency is the number of wave cycles to pass a given point per unit of time. the SI unit of cycles per second is called hertz (Hz). the wavelength snf frequency of light are inversely proportionate to each other. the product of the frequency and wavength is always a constant (c), the speed of light.
