For this lab we will be using "The Skate Park" simulation from PhET. You can run this simulation by clicking on the following image. This will open in a new window. You need JAVA to run this. If you have trouble, after installing JAVA, try copying and pasting the following link into a new window:

------------------------------------------------
How high must a 20 kg skater start at to have a kinetic energy of 360 joules at a height of 0 meters?
---------------------------------------
What is the total energy of the 60.0 kg skater before she starts her ride, 12 meters above the ground?
----------------------------------------------
If you throw a 2.0 kg basketball straight up in the air, at what height will the basketball have 160 J of potential energy?
----------------------------------------------
Describe what happens to the bar graphs when you change the amount of friction. Is the Law of Conservation of Energy still obeyed?
