These are our wonderful performance tasks

media type="file" key="real_jing_copy.swf" width="457" height="337" OUR GOAL !!!!!!!!
 * 1) Our GOAL was to create an rollercoaster demonstrating the 3 __Newton's laws__ and __forces__by making the rollercoaster out of recyclable materials.

the newtons cradle number 1
 * The pirate ship. **
 * The cart was suppose to go up and down . But instead it went straight through the hole. And it wouldn’t be very safe. And we didn’t have the right equipment .We also thought it would be very hard. **
 * We wanted to used it because it would have been really fun for the people who got to go on it . And it wouldn’t be a waste of money. **


 * The newton’s cradle didn’t work because it wouldn’t be fair **
 * for the people who waited a long time then it just finished it **
 * would have been a waste off money. Also the can wouldn’t **
 * stay still because off the wind. This is bad because the cart **
 * would miss it and cause an accident that could cause death. We **
 * all thought about it and we don’t want people to get hurt. **

﻿MATERIALS !!!!!!!!!!! Our rollercoaster was made out of cardboard for the base the top of a coke bottle for the funnel and part of a coke can ( to make the marble go __accelerate__ at the end) ﻿METHOD!!!!! . First of all we made the base out of an old cardboard box . then we made the tracks out of thin cardboard by shaping them into trough like tracks .made the __funnel__ by cutting out the top of a bottle and cellotaping it to the track above of it . made the loop by cutting down the sides of a peice of cardboard and shaping it until it was round .made the sharp turn by shaping cardboard .and putting a little wall that we made out of thick cardboard at the end. ** FORCES IN OUR ROLLERCOASTER !!!!!!!!! ** For our roller coaster we put the first Newton's law at the end because a __external__ force has been applied from the wall. We created this by making a wall out of cardboard at the end of our rollercoaster so the marble would immediately stop.

For Newton's law number two the mass of the marble and the speed of the marble __equals__ more force plus the slope of the hill to make a faster run for the marble.We found that the bigger the marble the better speed and force it has.We also put a loop in our rollercoaster so the acceleration was faster.

For Newton's law three we used a funnel because there is an equal and opposite reaction for every object.The marble is pushing against the funnel and the funnel is pushing against the marble like the __Wall of Death__.We made the funnel out of the top half of a bottle because we know that the top of a bottle had a different size than the rest of a bottle so it would create more of a build up of speed to to make the marble travel faster down the tube. Also the funnel create's __centripetal force__ because of the angle of the slope going into the funnel.Then __gravity__ is pulling the marble to the ground.

﻿CONCLUSION!!!!!!!! ﻿In conclusion i think our roller coaster was succesful because we reflected over the matrix and did everything we could to achiveve all of them.To improve our rollercoaster and everything else we did we needed to manage our time so we could of finished everything with out having to rush the presentation of our work.

SALES PITCH (forceatron) We belive that our rollercoaster is worth buying because it would be fun for tourist and people of all ages.Also it has a great education of newtons laws and different types of forces.Our rollercoaster has been tested and trialed for safety and to make sure there is no technical difficulties occur. This rollercoaster will be low cost to build and will not take years to get up and running.This rollercoaster is visually attractive and will draw peoples attention. You should buy our rollercoaster because it has amazing tracks that makes you fly like lighting and it will just be the time of your life and you'll defneately get a bang for your buck.

﻿FINAL COMMENT We used all the three newton's laws and two other main forces that are used an every day life.
