Question

When a roller coaster climbs up a hill, its potential energy?
	Increases
	Decreases
	Is zero

anonymous · Answer

a

friendzone · Answer

it decreases

anonymous · Answer

why?

friendzone · Answer

its going up the hill then stops

anonymous · Answer

the higher it goes up the more potential energy it accumulates

anonymous · Answer

ummm
potential energy increases as the kinetic energy decreases

anonymous · Answer

so as u r going up,kinetic energy will decrease n potential energy will increase

anonymous · Answer

the initial potential energy it gains is converted to kinetic energy when it goes down, then converted back to potential energy as it climbs up another hill.
means potential energy is increased
you read it wrong

anonymous · Answer

http://www.shs.d211.org/science/ips/project/coasterpageweb/Energy1.html it says there it increases

anonymous · Answer

lol
its basic,why'd you need links for?

anonymous · Answer

dunno

friendzone · Answer

The potential energy of the coaster decreases, but the speed and the kinetic energy ... Relative to the ground, the roller coaster has a very large potential energy (Fig. ... it goes down the hill, both the speed and the kinetic energy increase. ... the first "valley", it has a lot of kinetic energy, so it can climb up the second "hill".

sigh
okay guys
kinetic energy is inversly proportional to potential energy
so now wont you agree that kinetic energy is decreasing as its climbing up?

friendzone · Answer

so its decrease right

anonymous · Answer

@aajugdar is a wise man, I'd listen to him

anonymous · Answer

no
as kinetic energy is decreasing
potential energy will increase
because its inversly proportional
answer is A!
