Dimensional Analysis, Speed, Velocity, Acceleration and Free Fall. Review Outline:. Dimensional Analysis Problems (converting). What is speed?. Calculations using speed formula.. What is velocity? . 1.Superman is off to visit Lois Lane. He sees he’s late and increases his flying speed. I know he defies the laws of physics anyway, but let’s pretend, okay? If our lead-phobic super hero accelerates uniformly from 1200 m/s to 1600 m/s in 0.40 seconds, then what is his rate of acceleration? . PHYS 243. Giancoli. , Sec 2-1, 2, 3, 4. © . 2011, . B.J. .

Compare and Contrast Speed, Velocity and Acceleration. is the speed of an object in a particular direction. MYP Unit Question: What Moves YOU!!. Area of Interaction: Human Ingenuity. Displacement: . Is the distance from where you start to where you finish. . Δ. d=. d. f. -d. i. Velocity:. How fast and in what direction (vector quantity). V = ∆d/t. Speed: . How fast (scalar quantity). Velocity and acceleration Measuring an objects motion speed Speed is calculated by dividing distance by time S = d/t 5.0 km/h 2.5 m/s 45 mph velocity Velocity is the same as speed, but you tell the direction of motion in the answer. Acceleration is a change in velocity. Speed or direction. Centripetal Acceleration. Acceleration can mean a change in direction, not just speed. Centripetal acceleration. Acceleration that occurs in a circular motion. V. ector quantity: . magnitude (value) & direction. R. ate . at which an object changes its velocity. . “. How fast an object is getting faster”. If the velocity of an object is changing, it is accelerating!. Displacement: . Is the distance from where you start to where you finish. . Δ. d=. d. f. -d. i. Velocity:. How fast and in what direction (vector quantity). V = ∆d/t. Speed: . How fast (scalar quantity).
