 Equation for Average Velocity = ΔX/Δt Difference between speed and velocity Velocity is a vector; it has a magnitude and directionSpeed is does not have a directionVelocity is a measureĀ of displacement/timeSpeed is a measure of distance/time Equation for acceleration a = ΔV/Δt*must be instantaneous velocity*constant velocity means zero acceleration Relationship between position, velocity, and time for one-dimentional motion x = x0+v0t+1/2at2v2-v02 = 2aΔxv = v0+at Define acceleration, velocity, and deceleration Acceleration: How quickly the velocity changesVelocity: How quickly the position changes (net)Deceleration: Acceleration is in the opposite direction of velocity If you throw a ball straight into the air... How does acceleration apply? How does velocity apply? Acceleration is g at EVERY POINT in the throw, even at the top.Velocity is equivalent at the same point (y) during the throw, but will have the opposite direction (opposite sign)Velocity at the top will be 0 Authorvictimsofadown ID203500 Card SetPhysicsCh2 DescriptionPhysicsCh2 Updated2013-02-26T09:43:15Z Show Answers
