I got a question:
If a roller coaster is going up the hill (potential energy) then when it goes down it gets converted into kinetic energy by gravity right?
Also As you go down the first big drop of the roller coaster (gravity going downwards 9.81 m/s2) how does acceleration come in play?
I know when you go down a roller coaster at a certain point : gravity and acceleration balances each-other out giving the effect of 'weightlessness' but where does the acceleration come from?
Also can acceleration [Upwards] exceed the value of gravity[downwards] on a roller coaster?
My attempt: I think the acceleration comes from the downward effects of gravity as the roller coaster cart travels down the first big drop,,,, then gravity at -9.81m/s2[Down] and the acceleration of +9.81m/s2[Up] balance at a certain point giving the effect of weightlessness.
THANK YOU VERY MUCH!
