The ability to do work; it is released or absorbed during chemical reactions in the form of heat, light, electricity. units: calorie, Joule; 1 cal = 4.18 J 


A substance that occupies space and has mass. 


Measures gravitational force. Varies slightly on Earth, and significantly elsewhere. 


Energy due to position or stored energy 




The amount of matter. Never varies 


Depends on the skill of the person doing the measuring and the limitations of the measuring instrument. The last significant figure in a measurement is always uncertain.

Rules for multiplication of numbers in scientific notation. 

Multiply the first numbers and add the exponents. (3 X 10^5)(2 X 10^3) = 6 X 10^8 

Rules for division of numbers in scientific notation. 

Divide the first numbers and subtract the exponents. (8 x 10^6)/(2 x 10^10) = 4 x 10^4
