The slope of a roller coaster describes how steep the roller coaster is. Knowing the angle of the slope will tell you how steep a roller coaster is.
Newton's second law (Force equals mass times acceleration, F = ma) deals with acceleration so it "takes effect" every time that the roller coaster speeds up, slows down or turns (horizontally or vertically).Basically Newton's second law just says that the acceleration of an object is directly proportional to the net force applied to the object and inversely proportional to the mass of the object. Or, in other words, the harder you push the faster it speeds up and the bigger it is the slower it speeds up (or slows down - deceleration is an acceleration).This means that in your roller coaster example, the object is the roller coaster and the force can be: The motors that start the coaster and lift it up hills. The brakes that slow it down. Gravity which pulls it down the hills. The rails and wheels which cause the roller coaster to turn around bends, etc. At each of these points, Newton's second law is at play, determining how much acceleration will result from the force applied to the roller coaster's mass.
How do engineers force a roller coaster to speed up
Twister - roller coaster - was created in 1999.
The limiting frictional force is the force that slows down the tennis ball on the roller coaster.
centripetal force
Centrifugal force is used in a roller coaster.
When the roller coaster starts to stop your body wants to keep moving, that is inertia.
it is something you cant see but know and one place where could find it is on a roller-coaster
Millennium Force
That is because the roller coaster is designed to accelerate you with enough force to experience more than 1G acceleration. When upside down you are being pulled down with 1G but up with more than 1G so net force is up, not down. Some rides give you 2-3 G up force.
the one that moves the slowest
Brakes, and a lack of driving force.
