Eireann has spent some time researching the physics behind roller coasters! Well done Eireann!
At the start
of a roller coaster ride, the cart is pulled to the top of the first hill but
after that, the cart must complete the ride independently. The roller coaster is moved along the track
because the energy converts from potential energy to kinetic energy. The
roller coaster can be wooden or steel, the experience of the ride will change
depending on the material it is constructed with. They can be all shapes or
sizes. It may have a loop or it may not have a loop. Wooden roller coasters sway a lot more
compared to steel roller coasters.
Inertia allows the roller coaster to glide
along the tracks without an engine. Isaac Newton was the scientist who
discovered inertia, it was his first law of motion.
“An object
at rest tends to stay at rest unless acted on by an unbalanced external force.
An object in motion will stay moving in the same speed and same direction
unless acted on by an unbalanced external force.”
