Mouse Trap Reflection Construction How it was made: The car was made by cutting out cardboard for the body that would fit the mouse trap on top of it. The wheels were made out of cardboard, larger in the back and smaller in the front. Dowel rods were used as the axels and cut the straw in half to make it so the axel would be able to spin. Changes: One change that was made was to make the body longer. This change was made so a lever could be used on the mouse trap and be able to get the wheels to move. The results of the change were that the mouse trap and lever would be able to move the wheels.

Kinetic Theory Of Gases Postulates of the Kinetic Theory of Gases: A gas consists of a large number of tiny particles that are in constant, random motion The gas particles occupy a net volume so small in relation to the volume of their container that their contribution to the total volume can be ignored The collisions between particles and the walls of the container are perfectly elastic (no energy transfer) Kinetic Theory of Gases relates temperature to average kinetic energy Kinetic Theory of Gases (aka Kinetic Molecular Theory) can be used to explain the Gas Laws: Pressure-Volume Relationship (Boyle?s Law) P? 1/V or V ? 1/P (at constant n, T) Pressure-Temperature Relationship (Guy-Lussac?s Law) ?T, ?v ?v, ?P Volume-Temperature Relationship (Charles?s Law)

The difference between: Vectors and Scalars; and examples of each. Distance and Displacement; which is scalar? Which is vector? Speed and Velocity; which depends on direction also? **Can your speed remain constant but your velocity be changing? Explain. Two ways to have a constant velocity? Three ways to change your velocity? What is your acceleration when your velocity is constant?

Name ____________________ Date ___________?Mr. Carcich Physics 2D Motion Short Answers 1) Distinguish between rotation and revolution. Using the earth, provide an example of each. 2) Distinguish between rotational and tangential speed. What is their relationship? 3) If you are on the center of a merry-go-round, and you walk toward the outer edge, how does your rotational speed change? Your tangential speed? 4) When you whirl a can at the end of a string in a circular path, what is the direction of the force that acts on the can? 5) Does an object undergoing uniform circular motion accelerate? Why? 6) When a car makes a turn, do seat belts provide you with a centripetal force or centrifugal force?

Name ____________________ Date ______ Mr. Carcich CP Physics Current Electricity & Circuit Review Be sure you understand completely the following concepts. You need to know: Electric Current Define current. What are the units for electrical current? What is conventional current? What is drift velocity? Current- the rate of flow of electrical charges Conventional current- the flow that positive charges would flow (if they did flow), positive to negative Actual current- direction that electrons would flow, negative to positive Drift velocity- average velocity that a particle, such as an electron, attains due to an electric field What is necessary for a current to begin to flow? What must you connect to a circuit?

Gases and the Mole Gay-Lussac formulated the law of combining volumes. Law of Combining Volumes Gases at the same temperature and pressure react with one another in volume ratios of small whole numbers. Law of Combining Volumes Example 1: H2 + Cl2 2HCl 1 L + 1 L 2 L Law of Combining Volumes Example 2: 2H2 + O2 2H2O 2 L + 1 L 2 L Avogadro?s law The volume of a gas, maintained at a constant temperature and pressure, is directly proportional to the number of moles of the gas. Molar Volume the volume that a mole of gas occupies at standard temperature and pressure Molar Volume 1 mole of ANY gas at STP occupies 22.4 L. Sample Problem 1 What volume would 7 moles of carbon dioxide occupy at STP? = 157 L CO2 7 mol CO2 22.4 L 1 mol Change 228 L of O2 at STP to moles. 470 moles 426 moles

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

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
