Question

what is the law of conservation of energy

Answer 1

please can someone tells me what is law of conservation of energy

Answer 2

i need an example of an energy conversion , make sure to discuss which form of energy are involved ? :)

Answer 3

Energy can neither be created nor be destroyed, it can either be transferred or transformed from one form to another.

Answer 4

Most famous example is an object falling from a height transforms its P.E into K.E
\[mg \Delta h = \frac{1}{2}m v^2\]

Answer 5

for a isolated system the total amount of energy (kinetic, potential, electric, thermal,...) is constant. Isolated system means that there is no energy change with an external source. As you can pick a specific system to be isolates, you can also assume that the whole unierse is an isolated system. This is a general rule you can see this in various equations, or physical system. For example: the equation E=mc^2 is a result of this principle. Similar expressions can be seen in thermodynamic, classical dynamic and other field of study of physics.

Answer 6

I wrote the word "unierse" wrong above, i wanted to write Universe. And one more thing; mass itself is a form of energy.
