I have to discuss the Law of Conservation of Energy?

Question

What can i talk about (details)

like potential-kinetic

etc.

Answer 1

Law of Conservation of Energy:-

                                                         German scientist Robert Mayer states that energy can neither be created nor destroyed.

It may change from one form to another.It means sum of all forms of energies remains constant.

Interconversion of Potential and Kinetic energy.

1. When a body is thrown up with certain velocity,it possesses kinetic energy at this time. Due to this energy it does work against gravitational force and the work done is stored as the potential energy and at highest point,its velocity becomes zero hence the kinetic energy fully converts into potential energy.

2. A body kept above earth surface has the potential energy by the virtue of position when it left down it gains velocity, due to gravitational force. Its height reduces but the velocity increases, it shows that its potential energy is converted into kinetic energy.

                        In both above cases,the valid condition is

                                     1/2 mv² = mgh

Answer 2

The law of conservation of energy states that energy cannot be created nor destroyed it just changes form.

An example is an oven uses electrical energy and converts it into thermal energy
