Last class we went through how to calculate the speed of vehicles in motion by converting seconds into hours and feet into kilometres. Next we calculated the speed by doing the formula V=t/d.
We then learned the formula to calculate the average speed which is Vav=d/t. We did an example where we had to find out Juan's average speed in m/s and km/h. Here is a video to show how to calculate average speed: http://www.youtube.com/watch?v=y40aVo90ETE
This relates to the other topic that we did on observing what kind of motions we saw in the videos of skateboards, car race etc. because we were observing the motion and speed of the vehicles on the road and stating wether Juan's speed or motion was uniform or not.
Next is Aimee
