Then I used only two and it finished at the same points with the same amount of energy. The kinect energy was the same no matter the mass of the coaster. The potential energy is also the same because the velocity doesn't change no matter the mass.]]> 2017-01-23 13:24:27 UTC https://padlet.com/jboyle10/3aow4tcxj11k/wish/148694703 https://padlet.com/jboyle10/3aow4tcxj11k/wish/148696120 The amount of speed you have at the end matters. If you make the roller coster go up hill before it ends then it won't crash. If you decease the amount of kinetic energy it ends smoother. You need more potential energy during the end. ]]> 2017-01-23 13:29:50 UTC https://padlet.com/jboyle10/3aow4tcxj11k/wish/148696120 https://padlet.com/jboyle10/3aow4tcxj11k/wish/148696739 The total amount of energy stays the same throughout, so if you have to much kinetic energy, you need to add more height at the very end so potential energy is more than kinetic.]]> 2017-01-23 13:32:16 UTC https://padlet.com/jboyle10/3aow4tcxj11k/wish/148696739 https://padlet.com/jboyle10/3aow4tcxj11k/wish/148697800 If you add loops to your coaster, then it will decrease your energy, so that will help it not crash into the wall at the end. If you change the mass, it will not affect the speed or energy. If you move the hills up and down, the speed and energy will change and it might or might not crash.]]> 2017-01-23 13:36:16 UTC https://padlet.com/jboyle10/3aow4tcxj11k/wish/148697800 https://padlet.com/jboyle10/3aow4tcxj11k/wish/148699664 The higher your hill is at the beginning, the faster you will go after that. You lose energy when you add loops. If you change the mass, the speed nor the energy will be affected. How fast you're going at the end matters, so you don't crash. If you make your car go up hill at the end, you have the most DE at that point.]]> 2017-01-23 13:42:11 UTC https://padlet.com/jboyle10/3aow4tcxj11k/wish/148699664 https://padlet.com/jboyle10/3aow4tcxj11k/wish/148700161 If you start with a big hill and then let it go to just about the end and put a hill, the coaster slows down enough to not kill all passengers on board  and get sued, it stops in time.
