WORK, ENERGY, AND POWER Objective: 82 ? Describe the relationship between force, displacement, and work change in an object's motion is related to both force and how long it acts net force x distance = WORK WORK = the product of the NET FORCE an object and the DISTANCE through which the object is moved the heavier the load or higher something is lift, the more we do WORK IS DONE WHEN A FORCE ACTS ON AN OBJECT AND THE OBJECT MOVES IN TEH DIRECTION OF THE FORCE EXAMPLE: If we lift TWO loads up one story, we do TWICE as much WORK as we would in lifting one load the same distance because the FORCE needed to lift TWICE the weight is twice as great, and if we lift one load two stories instead of one story, we do twice as much work because the DISTANCE is twice as great

Chemistry Study Guide Unit 1: Measurement and the Methods of Chemistry Counting significant figures: 1) leading zeros never count 2) Trailing zeros only count if there is a decimal point written 3) All numbers that aren?t leading or trailing zeros count Unit 2: Atomic Structure, Periodicity, and Nuclear Energy Proton: +1 (charge) Neutron: 0 (charge) Electron: -1 (charge) Atomic number= number of protons within an atom Atomic mass= total weight of the atom. P+N If there is a power to the left of the element, that implies the mass. Isotope: same atom with same atomic number, but different number of neutrons. Different weight. Neutrons and protons are INSIDE nucleus. Electrons on orbitals. Valence electrons= electrons on outermost shell. The electrons that do all reactions.

Democritus Greek; said that everything in the universe starts with small pieces of un-cuttable (atomos) pieces of matter but had no proof ? Aristotle Greek; said there was no such thing as the smallest piece of matter; he was the good speaker therefore people of his time believed him John Dalton created the Atomic Theory in the 1800's The Atomic Theory says that all things in the world are made of atoms, and if the materials are the same, the atoms are identical especially in their mass; different elements have different atoms and a chemical reaction is a rearrangement of atoms William Crookes

1 Position(x, y or z) Displacement (?x, ?y or ?z) Change in position. Depends only on initial and final positions, not on path. Includes direction. ?x = ?vdt Velocity (v) Displacement per unit time Average velocity vave = ?x/?t Instantaneous velocity v = dx/dt ?v = ?adt Acceleration (a) A change in velocity: speeding up, slowing down, or turning. Average acceleration aave = ?v/?t Instantaneous acceleration a = dv/dt Problem: Acceleration (B-1993) 1. In which of the following situations would an object be accelerated? I. It moves in a straight line at constant speed. II. It moves with uniform circular motion. III. It travels as a projectile in a gravitational field with negligible air resistance. (A) I only (B) III only (C) I and II only

SI unit: coulomb (C) Quantum of charge: the proton charge (e) the electron charge (-e) e = 6.02 ? 10-19Coulombs Conservation of Charge The net charge in any process or reaction remains unchanged. Coulomb?s Law Calculates magnitude of force between charges Force is repulsive if charges have the same sign. Force is attractive if charges have opposite signs.

Chapter 7 ? Rotational Motion and the Law of Gravity This chapter deals with rotational kinematics ? the relationships between rotational position, velocity, acceleration and time. Rotational dynamics will be discussed in the next chapter. Dynamics deals with energy, momentum, and forces. Universal gravitation is also discussed in this chapter in part since satellite and planetary motion involves rotation. Angular displacement, velocity, and acceleration Angle (() can be defined in terms of radius (r) and arc length (s) on a circle as
