The coolest roller coaster ever built is.....

Xy Turtle Blazer, and for those of you that guessed King Da Ka, you're all wrong. You see, in science class we made rollercoasters out of home materials(paper towel rolls, shoe boxes, plastic bottles, wrapping paper rolls, etc.). Anyway, how does this connect to science? Well, it actually relates to frictions, forces and Newton's laws. You see, Newton's first law states that an objectat rest will remain at rest and an object in motion will remain in motion at a constant velocity unless acted upon by an unbalanced force. So, the marble is still at the beginning, but then when we push it it will start to roll and will remain at a constant velocity until it goes down a hill to gain greater speed. Newton's second law states that Force=Mass x Acceleration. So, for the weight of the marble to go faster our rollercoaster will need to give the marble a greater force to act upon, for example maybe a really steep hill. Finally, Newton's last law states that for every action there is and opposite action. So, there isn't much in this project, but when I push the marble my hand goes back one way while the marble goes forward. So, this is a really fun,hand's on learning project that maybe you should ask your teacher about. Until next time, this is Bigdog, and stay in school!!
