ccording to energy of conservation, energy can't create or destroy.
So, where does the Gravity in Earth come from??

[?] [?] It really is simple. Potential energy is just that - potential energy. You can convert it to kinetic energy and back, but you don't ever get anything for free. It does not violate conservation.Originally posted by way2go
On the other hand, a bit philosophical though, gravity only exists if a body has gravitational potential energy. What's your comment on that?
The question might look simple, but too me it isn't.
The law of conservation of energy states that energy cannot be created or destroyed, it can only be transformed from one form to another.
No, according to the law of conservation of energy, energy cannot be created out of nothing. It can only be converted from one form to another.
In everyday life, this law applies to all energy conversions, such as when we use electricity to power our devices or when we consume food for energy. The total amount of energy remains the same, it just changes form.
No, energy cannot be destroyed. It can only be converted into a different form, such as heat, light, or motion.
The law of conservation of energy was first proposed by a German physicist, Julius Robert Mayer, in 1842. It was later confirmed and further developed by other scientists, including James Joule and Hermann von Helmholtz.
