Describe the law of conservation of energy. give two examples of energy being transformed from one type to another

The law of conservation of energy states that the Total Energy in a system will remain constant in an isolated system. Energy can only transfer. The law of conservation also states that energy can neither be created nor destroyed and that is a ambit concept in physics.

Some examples:

When a person eats, their bodies will convert chemical energy from food into mechanical and electrical energy so that the person can move.

Use an example of any machine, for example:
A blender transforms electrical energy into mechanical energy
