In Unit 4 so far we have had a lab practical and have a test this Monday. The lab was fairly easy, all we had to do was... Roll a ball down a ramp and through 2 speed laser magic time recording things. Basically they tell you how fast an object is going in m/s without having to make them one meter apart. Anyways we had to roll the ball through these to find the velocity then based on the height of the table where the lab was set up we had to calculate how far the ball would go before it smacked the floor. Again we have to use the set up

D
A
T
V
Vo

and majority of the time when finding how far the object will dravel we'll be using the equation D=1/2AT^2+VoT. This equation will pop up a lot during unit 2, 3 and 4 so get used to it! In unit 4 I have really learned how to use this equation well. I can pretty accurately tell you where your object will land :D
