Last week‚ my group and I were constructing the roller coaster. I contributed by installing my funnel into the coaster. I did this by making adjusting the track so that it would lead the marble to the border of the tube. I did this because learned that when the marble spins around the edge of the tube‚ it increases the time which was what we wanted. After adjusting‚ I put supports on the funnel that would help the funnel maintain its shape to have the most maximum time possible. I also contributed

February 23rd‚ 1855. II. Statement of the Problem The purpose of this experiment is to find out the relationship between the spacing of the magnets in a Gauss Rifle and the velocity of the last ball‚ and use it to determine the maximum velocity that can be achieved. III. Significance of the Study It is important for us to know whether the spacing in-between magnets would affect the overall velocity of the last ball. This will give us accurate measurements

will have a curve showing increasing speed or in other words‚ increasing velocity over time. Therefore‚ the results shown in the velocity vs. time graph will have a positive linear slope. The acceleration vs. time graph will then have no slope and just a straight line because the change of velocity is relatively constant. In conclusion‚ when the mass of the weight increases‚ the acceleration won’t and only the speed and velocity over time will change. Materials -Laptop computer -Smart pulley -Retort
