Question

I just want to clarify..

Is Potential energy the energy of an object at REST?

Answer 1

yeah

Answer 2

NO .. potential energy of an object, is defined by its position .. that is it
kinetic energy on the other hand is defined by its velocity


for example, when u throw a ball up, the k.e gets converted into p.e right? when the ball is IN MOTION.. it keeps getting p.e right?

so p.e only depends on WHERE the object is, and doesn't matter whether or not, the object is moving or rest!

Answer 3

ope my bad sorry about that

Answer 4

exactly, that's why i got confused a lil' bit with the other definitions
thanks!

Answer 5

yea remember.. objects can always have k.e and p.e together.. (so obviously its in motion)
p.e is a little harder to deal with, cause p.e depends on origin :P..

Answer 6

oh ok
one more thing..
They said that gravitational energy deals only with vertical motion of an object.
so i 'm wondering if a potential energy, not gravitational potential energy, can deal with horizontal motion..is it?
