Magnitude of A : |A|= Ax : is the magnitude of the x-component Ay: is the magnitude of the y-component *Direction of A: * Given two vectors A and B (Cross product) (Dot product) Basic Mechanical Quantities • Mechanical quantities can be expressed in terms of three fundamental quantities: (in the SI system) mass kilograms (kg) length meter (m) time seconds (s) • The denisty of a substance is defined as its “mass per unit volume”: mass rho (density) volume * The number of atoms in one mole of any element or compound is called Avogadro’s Number, NA , which has the value 6. 02 x 1023 atoms /mole. POWERS OF TEN VERY LARGE NUMBERS (Astronomy, High Energy Particle Accelerators) or VERY SMALL NUMBERS (cells, molecules, atoms, nuclei, quarks) it is most convenient to use "Powers of Ten" notation. • VERY LARGE NUMBERS: 103 106 109 1012 kilo (k) mega(M) giga(G) tetra(T) ten to the three (thousand) ten to the six (million) ten to the nine (billion) ten to the twelve (trillion) ten to the minus three (thousandth) ten to the minus six (millionth) ten to the minus nine (billionth) ten to the minus twelve (trillionth) • VERY SMALL NUMBERS: 10 -3 10 -6 10 -9 10 -12 milli (m) micro(μ) nano(n) pico(p) Electron-Volt: • An electron volt is a measure of energy. An electron volt is the kinetic energy gained by an electron passing through a potential difference of one volt. • A volt is not a measure of energy. An electron volt is a measure of energy. • An electron volt is very tiny. 1 e. V = 1. 602 x 10 -19 joules ke. V (Generally using some experimental Physics, i. e. Solid-State P) Me.
