Bell Ringer: What is speed?

• • Speed

    • Rate of movement

    • v = d / t (speed = distance / time)

    • Units for speed: distance unit / time unit or distance unit "per" time unit

      • In SI system, we usually use m/s for speed

    • Speed practice

      • At what speed can you "moonwalk?"

      • How long would it take you to "moonwalk" to the moon (384.4 x 10^6 m)

  • Measuring motion lab

    • • measuring and graphing the motion of a bowling ball and a skateboard

      • can be found in the file cabinet
