there is gravitational potential energy in the marble when it's on the top of the roller coaster which could be represented by Ep=mgh
the gravitational potential energy in marble transformed into kinetic energy and thermal energy.
We are able to use the kinetic energy we need to make our roller coaster effective and efficient.
The tubes right here are our innovative design pieces, they make the roller coaster interesting that the passengers are able to have a more excited because of the darkness
The law of conservation of energy states that energy could neither be created nor destroyed within the system.
we are able to change the velocity of the marble by changing the height which relates to potential energy and it helped us to make our roller coaster more effective and efficient.
The design concept of our roller coaster is to create a roller coaster ride with a theme of winter.
Thanks for watching
