If you have a 500 kg coaster and a 200 kg coaster they will have the same results and same amount of energy. There is the most potential energy when they are going up hill but not when they are going down. There is the most Kinetic energy when it is going down hills when there is not very much potential energy. There is the most DE energy on straight aways like on the end when it is going back into the station. If your loops are higher than the ones before it then it will get stuck and not be able to get up and finish. Lastly the amount of energy satays the same the entire time whether it is PE, KE, or DE there is always the same amount. ]]> 2017-01-23 13:24:25 UTC https://padlet.com/jboyle10/Ener1/wish/148694690 https://padlet.com/jboyle10/Ener1/wish/148697281 You can not have any other hill taller than the first hill because not enough energy will be built up to keep it going. Also there has to be limited energy when the cart is about to stop because other wise it will blow right through the ending point. The most potential energy is when the cart is at the top of the first drop getting ready to start going downward. It has the most kinetic energy at almost the bottom of that hill and same with speed because it just went down a really big first hill. This experiment was fun to do and helped me learn more about potential and kinetic energy. ]]> 2017-01-23 13:34:20 UTC https://padlet.com/jboyle10/Ener1/wish/148697281 https://padlet.com/jboyle10/Ener1/wish/148697823 2017-01-23 13:36:21 UTC https://padlet.com/jboyle10/Ener1/wish/148697823 https://padlet.com/jboyle10/Ener1/wish/148698957 When building the coaster you need to have a big hill at the beginning. You need to make sure there is a loop so it slows down and absorbs energy. The top of the hill is where the most potential energy is. The highest Kinetic energy is at the beginning of the loop and the highest D energy is the end. At the end of the roller coaster you have to make sure it doesnt crash. The end of the coaster should have a hill to take some energy away to make sure you don't crash.]]> 2017-01-23 13:40:05 UTC https://padlet.com/jboyle10/Ener1/wish/148698957 https://padlet.com/jboyle10/Ener1/wish/148699483 To create a successful coaster it is important to know a few things for the coaster to work. To get the total energy for the whole roller coaster you must have the biggest hill at the beginning so that the coaster has enough energy to make it through the rest of the course. While traveling up a hill, there is the most PE. When you are traveling down hill there is the most KE. DE is when the coaster is traveling straight. It is important to slow down the coaster near the end so that it doesn't crash. To do this you need to make hills in order to waste energy so that you will have just enough to safely complete coaster.]]> 2017-01-23 13:41:35 UTC https://padlet.com/jboyle10/Ener1/wish/148699483 https://padlet.com/jboyle10/Ener1/wish/148699771 After building multiple coasters I found that in order to have it successful you have to have a big hill at the beginning to start off your energy and then you want to add another hill or loop that isn't too big but still takes away some of your energy to slow you down. You have the most Kinetic energy at beginning of the loop or hill. After you have the second hill you have to have a flat part or a smaller hill you get to reach the end of the roller coaster.]]> 2017-01-23 13:42:28 UTC https://padlet.com/jboyle10/Ener1/wish/148699771 https://padlet.com/jboyle10/Ener1/wish/148875663 When building your coaster, you should keep your hill sizes in mind. The first hill should be the biggest so it can get as much energy needed to take the coaster through your track. As the coaster goes uphill, the potential energy starts to build up. Once the coaster overcomes the hill and starts going down, the kinetic energy kicks in and causes the coaster to pick up speed. Some tips that I have would be to start with the biggest hill and end with a loop and flat track to take away the speed. This should help you avoid a crash with your coaster. ]]> 2017-01-23 21:10:59 UTC https://padlet.com/jboyle10/Ener1/wish/148875663 https://padlet.com/jboyle10/Ener1/wish/149785636 I noticed that you can't have any hills higher than your first, because you won't have enough P.E. stored up to make it over the higher hill. I also noticed that the longer the track is, and the more loops you have, the more dissipated energy you will end up with. When the coaster is at teh top of the first hill, it has the most P.E., and the least K.E. At the bottom of the first hill, all of the P.E. has turned into K.E. As you build your track, you have to keep in mind that dissipated energy is both good and bad, it stops you at the end of the ride, but too much dissipated energy and your coaster will get stuck.]]> 2017-01-27 00:05:31 UTC https://padlet.com/jboyle10/Ener1/wish/149785636 https://padlet.com/jboyle10/Ener1/wish/153603973 2017-02-14 01:22:06 UTC https://padlet.com/jboyle10/Ener1/wish/153603973
