Question

give a mathematical formula for law of conversation of energy ​

Answer 1

Explanation:

If you know the potential energies for the forces that enter into the problem, then forces are all conservative, and you can apply conservation of mechanical energy simply in terms of potential and kinetic energy. The equation expressing conservation of energy is: KEi+PEi=KEf+PEf.

Answer 2

Answer:KEi +PEi =KEf +PEf.

Explanation:If you know the potential energy for only some of

the forces then the conservation

of energy law in its most general

form must be used :KEi+PEi+Wnc+OEi=KEf+PEf+OEf, where OE stands for all other energies.
