monday 9-21-09 Acceleration

1 comment:

  1. Concept of Acceleration
    Definition: any change in velocity
    Units: m/s squared
    Equation: acceleration= change in velocity divided by time

    Today we went over what acceleration means.

    What is the value of acceleration for a falling object?
    g=10 m/s squared

    How fast is an object falling after 3 seconds?
    1)identify concepts:speed/velocity. acceleration (gravity)
    2)Identify Units: t=3s, g=10m/s squared
    3)Write Symbols: t, g, v, a
    4)find an equation: v=g x t
    5)plug and change: v=30m/s

    How far does an object fall in 3 seconds?
