Explain these coasters physics wise

how does supreme scream work physics wise? as well as excelerator boomerang silver bullet and wind seeker thanks

I am not sure about those specific coasters but the principle of all coasters is generally the same

since the cars of a coaster are UNPOWERED hence the name coast

the way they operate is they are raised up high enough initially to give it POTENTIAL ENERGY to keep the cart moving as it moves up and down the hills of the coaster

you will also note that the INITIAL HILL of any coaster is ALWAYS THE LARGEST.. take the COMET in crystal beach canada it was the largest coaster for a while wooden one and it was many hundreds of feet up I think this allowed it to gain alot of speed.

now if you lift something up IT GAINS potential energy ..

when you let it fall then this potential energy is converted to KINETIC ENERGY that means MOVING ENERGY.. and thus gives the coaster speed..

the steeper the hill the FASTER IT speeds up or accelerates..

assuming 0 friction the coaster would have the same speed if it was a steep slope or a gradual slope but there is always some friction and the longer the track is the MORE friction and the slower the speed so the gradual sloped track in reality usually has LESS speed at the bottom of the drop then a steep slope

when it hits the bottom of the drop the track pushes the cart back up this means it now looses speed again as it climbs a hill.. but IF there is no MOTOR in the cart then it can NEVER GO higher than it originally was dropped because by the time it reaches the point it was dropped it will have 0 SPEED and thus wont be moving anymore...

so the designers of the roller coasters put the big hill first then make the other hills much smaller to keep the speed of the coaster to where a human can enjoy it.. as the coasters were made of steel later on they were able to make faster and faster coaster and thus make the hills bigger and the turns sharper..
