Science: Skate Park Assignment!

When distance changes then the kinetic and potential energy will decrease or increase. When you are going down then there is more kinetic energy because the skater is moving faster. When you move up then you have more potential energy because you are changing the distance from the ground. Kinetic and Potential energy interact with each other when potential is at it's greatest and kinetic is at it's lowest (or the opposite). Imagine a car going up hill it has more potential energy and then the car goes down a steep hill then it has a lot of kinetic energy. Energy can be transformed into the real world by a roller coaster, when the coaster going up a hill it has lots of potential energy because it is changing the distance from the ground (getting higher and higher). When it drops down then it the coaster goes fast because it has lots motion/speed. Friction affects the motion of objects by the surface the object is on and the object rubbing against each 


other. http://phet.colorado.edu/
