P = mgh
The spring potential energy of spring when it is stretched x distance from its natural length is given as
\(P = \frac{1}{2}kx^2\)
\(K = \frac{1}{2}mv^2\)
K is kinetic energy, v is the speed of the object, m is the mass of the object.
Explanation:
So, from the above concept, it is clear that total mechanical energy is the sum of potential energy and kinetic energy.
So, the answer is the Sum of Kinetic Energy and Potential Energy.

Important Points
Advantages of Biogas -
Thus, Biogas is a non-conventional type of natural resource.
Additional Information
There are basically two sources of energy:
|
Renewable resources or Non-Conventional |
Non-Renewable resources or Conventional |
|
The resources can renew themselves or can be used again and again. |
The sources cannot be replaced or reused once they are destroyed. |
|
Renewable resources are replenished naturally and over relatively short periods of time. It is present in unlimited quantity |
These are limited resources and consume millions of years to make. So these are used limitedly. |
|
It has low carbon emission and is hence is environment friendly. |
These are not environmentally friendly because the amount of carbon emission is high. |
|
The cost is low. |
The cost of these resources is high. |
|
A large land area is required for the installation of these plants. |
Less land requirement of installation of these plants. |
|
They require high maintenance costs. |
They require low maintenance costs. |
|
Example: soil, water bodies, sun (solar energy), wind, tidal energy, atomic energy, geothermal, forest, mountains, biogas, wildlife, atmospheric resources. |
Example: coal, oil, nuclear energy, petroleum, natural gas, LPG, batteries, shale gas, soil and phosphate are some examples. |
