Question

The conservation of mechanical energy says that the initial potential energy of an object plus the final potential energy of the object equals the initial kinetic energy of the object plus the final kinetic energy of the object.

true

false

Answer 1

As i mentioned in the previous post

the conservation of energy says that the total energy (kinetic and potential) of 1 state must be equal to the total energy of the 2nd state

Answer 2

so
KE1+PE1 = constant = KE2+PE2

Answer 3

what your problem has written is incorrect
PE1+PE2= KE1+KE2

Answer 4

ok false

Answer 5

@sooobored

Answer 6

yes...

Answer 7

thank you!
