AP Newton's Laws Review Sheet Newton's First Law (AKA Newton's Law of Inertia) ?Consider an object with no force acting on it. If it is at rest, it will remain at rest; if it is moving, it will continue to move in a straight line at a constant speed? 5 Everyday Forces Weight Fg = mg (direction is always down) Normal Force Fn (direction is always perpendicular to the surface Friction Ff = ?Fn (direction always opposes direction of motion) Applied Force FA (pushing or pulling) Tension FT (direction is always along the string or rope; tensions are equal on either side of a massless, frictionless pulley)

AP Kinematics Review Sheet Basic Terms: Position ? Location (sometimes in x and y coordinates) Displacement ? Distance and direction from initial position Speed ? Rate of change of displacement; magnitude only Velocity ? Rate of change of displacement; direction and magnitude; v = ?x/?t Acceleration ? Rate of change of velocity; direction and magnitude; a = ?v/?t For graphs of position versus time, velocity versus time, and acceleration versus time: Velocity is the slope of a position versus time graph Average velocity ? only use the first and last points Instantaneous velocity ? use the slope of the tangent line to the curve *The area under a velocity vs time graph equals distance acceleration is the slope of a velocity versus time graph

CHAPTER 6 REVIEW NAME_________________________________________ 1) Can work be done on a system if there is no motion? A) Yes, if an outside force is provided. B) Yes, since motion is only relative. C) No, since a system which is not moving has no energy. D) No, because of the way work is defined. Answer: D Diff: 1 Type: BI Var: 1 Page Ref: Sec. 6.1 3) If you push twice as hard against a stationary brick wall, the amount of work you do A) doubles. B) is cut in half. C) remains constant but non-zero. D) remains constant at zero. Answer: D Diff: 1 Type: BI Var: 1 Page Ref: Sec. 6.1
