Question

Name two forms of mechanical energy. Define the SI unit of energy.

Answer 1

kinetic energy and potential energy
sum of kinetic and potential energy is mechanical energy and it is always constant and SI unit is joule

Answer 2

There are many types of energy in our planet.

And the mechanical energy is one of the most important type of energies.

Mechanical energy is the type of energy which is the reason behind the movement of any physical object.

It is basically the sum of kinetic energy and potential energy.

There are also two main sub-divisions of mechanical energy.

1)Motion energy.

2)Stored mechanical energy.

And the SI unit of the energy is joules which is equals to 1 watt per second.
