When a roller coaster picks up speed going down a hill over time, this is known as acceleration. Acceleration can also include slowing down or changing direction in turns or loops.
A rollercoaster is a train kinda thing on a track that goes upside down :L
A rollercoaster is pulled up the first, highest hill, then it coasts all the way back to the start. A rollercoaster is heavy because of the weight of all the people, this mass plus momentum keeps it going over the successive smaller hills.
a ROLLERCOASTER
The first 'hill' on a rollercoaster is always the tallest - to give the cars the momentum to carry them to the end of the track.
Turn wheels to edge of road. If car starts to roll backward down hill, it will back off of the road.
The velocity at the top of the first hill was 21 m/s.
a sub heading is a heading that breaks down a subject into sections
A rollercoaster works by making use of gravity, hence the initial large hill you go down or magnetically-powered "rail-gun" launch at the start of the ride. A rollercoaster does not have any form of propulsion in the cars themselves, inertia is the only thing that keeps it going, without careful track planning a rollercoaster can actually stop somewhere along the track because it runs out of kinetic energy!
Grade Logic Ccontrol' is a car system that controls descents, which means the car doesn't 'run on' when you're heading down a slope. The transmission changes down a gear and reins you in to a safer speed. Heading up a hill, the transmission selects the best gear and stays there without 'hunting' back and forth.
it makes it go up then down then up then down... like a rollercoaster! :D
A hypercoaster can mean two things. It can mean a rollercoaster that has a drop of over 200ft, or it can mean a rollercoaster that has these three features:A height of 200-299 feetLacks inverting elementsA lift hill, not a launchHyper coasters have different restraintsThe related link has more detail.
i whent down the hill.
