 what is a standard? an exact quantity that people agree to use for commparisons an exact-----------used for comparisons what is length? distance between two points ------between two--- what does the SI use for length? meters hehe- u don't get a hint what does English use for length? feet hehe- u don't get a hint what is volume? the amount of space occupied size what does the SI use for volume? cubic meters hehe- u don't get a hint what does English use for volume? gallons they sell milk by the ----- a liter occupies the same--- as---? volume, cubic decimeter hehe- u don't get a hint a cubic decimeter is apart of what system of measurement? metric hehe- u don't get a hint what is mass? the amount of matter in an object matter is made up of mass what is the SI for mass? kilograms hehe-u don't get a hint weight=? mass*gravity an equation what is densisty? mass per unit volume of an object not which one is heavier what is the Eng. for mass? slugs u never hear it has to do w/ baseball what does the Eng. use for mass? weight hehe-u don't get a hint what makes an object fall? its mass hehe- u don't get a hint what does SI use for time? seconds hehe-u don't get a hint what makes something have weight? (view hint) has to be clinging to something (earth) and if it's separated from that "something", it falls clinging and falling what is time? interval between two events hehe-u don't get a hint what does the Eng. use for time? seconds hehe-u don't get a hint what is the SI for weight? newtons named after a scientist what doesn't make an object fall? weight hehe- u don't get a hint what is weight? meausrement of the force of gravity acting on an object has to do w/ gravity (think scales) what is the Eng. for weight? pounds (lbs.) hehe- u don't get a hint what does it mean to be weightless? that its so far from its object that is doesn't fall ex: being is space hehe- u don't get a hint in what direction can u not fall? down most common direction used for falling what does down mean? direction that gravity falls or towards the center of the earth hehe- u don't get a hint what is temperature? the measurement of the average kinetic energy of matter hehe- u don't get a hint what is SI for temperature? kelvin (k) metric what is the Eng. for temperature? Farenheit (F) celcius (C) what are derived units? units obtained by combining other units hehe-u don't get a hint what are conversions? the process of transfering one unit to another hehe-u don't get a hint how do you convert Celcius to Kelvins? C=K-273֯֯ an equation how do you change Fahrenheit to Celcius? F=9/5 C+ 32֯ an equation what is aboslute zero? 0 Kelvin hehe-u don't get a hint can you ever get to absolute zero? no hehe-u don't get one what is extrapolation? an estimate based on already known points on a graph has to do w/ graphs is it hot 10 miles from the sun's outermost surface? no is there matter in space? whats temperature why is it not hot 10 miles from the sun's outermost surface? because there is no oxygen or matter in space- to create heat you need to oxygen to burn matter hehe-u don't get one what can and can't travel through space? (why?) can: light can't: heat- has to pass through on object hehe-u don't get one how do you conversions? (view hint) 1) put the 1's digit in the original unit 2)put the decimal to the right of the column 3)place one digit per column 4)slide the decimal to the destinantion digit-stays on the right side of the column 5)fill in the empty spaces w/ zereos 5 steps what does SI stand for Internation System of Units hehe-you don't get a hint
