UNIT 03  Work, Power & Energy STUDY GUIDE 
BIG IDEA: Work is only present when a force is applied to an object and that object moves: No movement = no work. This class will primarily focus on work done in ONE direction. Work can be positive or negative:

Formulae: 1) W = Fx (where F is a force applied in the x direction and the object moves a distance of x meters) 2) W = Fcosθ (where F is a variable force applied in the x direction and the object moves a distance of x meters, so angle <> 0) 3) W = ∫F dx (where F is a variable force applied in the x direction and the object moves a distance of x meters, so angle = 0) 4) W = ∫F cosθ dx (where F is a variable force applied at an angle θ to the x direction and the object moves a distance of x meters) 5) Kinetic Energy work theorem: W = ∆KE.
Our good friends at Georgia State University (as is often the case) have a very good mathematical description of our various work formulae. Check out hyperphysics
