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?

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

Yareisa : even now I still change my opinions, there is no definitive G? : well, I'm not completely on the same wavelength as you and apollo, but I like it here. Yareisa : hi time G? : I will be back G? : hi time T Yareisa : good, we like you TimeTravel_0 : greetings G? : thanks Yareisa : yw Yareisa : you've been initiated G! G? : sorry I can't stop to chat Time, but it's way past my bed time G? : I have? TimeTravel_0 : no problem Yareisa : oh yes...I'll make sure you have plenty of experience! Yareisa : lol G? : thanks... I think. LOL ~) Yareisa : well I have been awake for 24 hours! G? : oh what the heck. maybe I will stop and introduce myself to time.... Yareisa : good! new I could persuade you! Yareisa : knew G? : LOL

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

10 AP Human Geography Outline Ch. 1 Thinking Geographically Key Issue 1: How do geographers describe where things are? Map- a two-dimensional model of Earth?s surface, or a portion of it. Place- a specific point of Earth distinguished by a particular character. Region- an area of Earth distinguished by a distinctive combination of cultural and physical features. Scale- the relationship between a map?s distances and the actual distances on Earth. Space- the physical gap between two objects. Connections- relationships among people and objects across a barrier of space. Cartography- the science of map-making. -Earliest surviving maps are from Babylonian clay tablets, (c. 2300 B.C.) -Aristotle was first to demonstrate that Earth is spherical.
