M3EP1 and the Ticker-Tape Machine

M3EP is currently involved in learning about the motion of objects. In lab, they used a ticker-tape machine to record the change in velocity of a trolly rolling down a ramp. The machine puts a dot on a piece of paper every 50th of a second. This piece of paper and the interval between the dots can be used to find the acceleration of different objects. It was a great success and the activity definitely reinforced a difficult concept -acceleration.
