# In life because it helped me make something that

In conclusion, in this project, the roller coaster was pretty successful. My main hypothesis stated that “if I make the roller coaster high enough, the loop will be successfully made the marble will go around the loop. That is because the marble would have more velocity than if the roller coaster’s starting point was lower.” That actually was correct and worked perfectly because the Potential energy did transform to the kinetic energy. My data shows that ? times the roller coaster did go around the loop and ? times it didn’t. My driving questions showed what the problem was which was the starting point to a perfect angle so the marble goes around the loop. My data shows the average time, loop radius, Height rise, and If the loop worked. The Final conclusion of the data was the radius needed to be about 3.0 meters, the height rise need to be about 1.28323, the average time for my roller coaster is 3.5 seconds, and finally the loop did work. Although the roller coaster project worked successfully, now I know I should have not wasted my time on one thing and multitasked so the roller coaster could have finished faster instead of right on time. To my surprise instead of buying some materials If connected to real life situations, this project may help me with real life because it helped me make something that I thought I would never make and would fail. I didn’t give up doing the project and in conclusion, I successfully finished it without any errors. This roller coaster project included the 3 laws. Newton’s 1st law (Law of Inertia) states that the object that is at rest will stay resting and the object in motion will stay in motion unless it is acted upon another force. The roller coaster starts with it being at rest and staying still because there are balanced forces acting upon the roller coaster (gravity). The unbalanced force of the track pulls the roller coaster in the direction of the track’s movement. Once the train moves off the first vertical bend, it continues in the direction it is moving around the track, until it is acted upon by the force of friction which slows it down,to a stop. The second law states that an object will accelerate the direction it was moved. The second law applies to the roller coaster because of the acceleration. The amount of force applied by the track is based on the mass of the track which is kept fairly consent by passengers. The roller coaster gains speed and heads in the direction. The thirds law states that for every action, there is an equal/ opposite reaction. The application to the roller coaster is when the roller coaster moves. When the wheels push against the rails, the roller coaster moves forwards.  The action force of the pushing wheels meets the reaction force of the rails, which in turn pushes the entire train forward
