Damon Pryor Physics Notes 2.7-2.9, Chapter 3 12/13/06 Free Fall Acceleration: The constant rate at which an object accelerates downward. It occurs on a vertical axis not a horizontal one, and is positive when traveling up but negative when traveling back down. g : the unit used to measure the rate of free fall as well as it’s magnitude 9.8 (or 9.81): Gravity Vector: Has magnitude and direction (ex: velocity, acceleration). Vector Quantity: A quantity that can be measured with a vector because it has magnitude and direction. Scalars: physical quantities that do not involve direction, which we deal with by using simple algebra. Displacement Vector: a vector that represents displacement (duh) Vector sum (resultant): is the combination of ab +bc = ac. Or properly noted :

Vector Subtraction: Component of a vector: is the projection of a vector on an axis. Resolving the Vector: the process of drawing two perpendicular lines to find the x component (the projection on the x- axis) the y component (the projection on the y axis)
