Week - Study Guide ?? PHYS The material for our third week comes from FlipIt Unit - From Unit we will discussion uniform circular motion on Monday For uniform circular motion from the textbook Chapter Sections expect for ??Tangential Acceleration ? in section For Newton ? s Laws Chapter Sections - ?? The textbook has many great worked out examples which are helpful to work through First try to solve the problem on your own and then look at the solution when you get stuck Just reading through the solution will do very little for your understanding ? Chapter examples - through - ??

Uniform Circular Motion Unit State the magnitude of the centripetal acceleration and explain what the variables represent - Describe both qualitatively and quantitively how the angular speed speed velocity and acceleration of an object undergoing uniform circular motion change over time Draw the velocity and acceleration vectors for an object undergoing uniform circular motion - Calculate the period for an object undergoing uniform circular motion - Calculate the velocity and acceleration for an object in uniform circular motion at any point in its motion i e be able to decompose the velocity and acceleration vectors into components ? Newton ? s Laws Unit State and explain Newton ? s st law of motion and identify situations where it is applicable to an object - State Newton ? s nd law of motion as well as identify and explain each of the terms and variables - Explain how the direction of the net force and the acceleration for an object are related - Explain and determine how the velocity changes when an object has a net force - State the three fundamental SI units as well as express quantities such as velocity acceleration forces ? in terms of the fundamental SI units State Newton ? s rd law of motion and apply it to determine whether two forces are a Newton ? s rd law pair - Calculate the net force on an object which involves determining all forces acting on an object breaking down individual forces into x y components and calculating the net force in the x y directions Apply Newton ? s nd Law to
