Question

What is the law of conservation of energy ? Prove logically with an example

that energy is always conserved ?​

Answer 1

$\huge\fbox{Answer}$

Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant.For example, when a pendulum swings upward, kinetic energy is converted to potential energy.

Answer 2

Answer:

Law of Conservation of Energy Examples:

Explanation:

In a torch, the chemical energy of the batteries is converted into electrical energy, which is converted into light and heat energy. ... Hence, the potential energy of water is converted into the kinetic energy of the turbine, which is further converted into electrical energy
