All types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.
<h3>What is kinetic energy?</h3>
Energy is the ability to perform a given work. Kinetic energy is energy in movement, whereas potential energy is stored energy.
For example, plant photosynthesis makes reference to chemical energy (potential energy), popcorn makes reference to thermal energy, etc.
In conclusion, all types of energy can be resumed into two basic types of energy which include kinetic energy and potential energy.

Answer: Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
Explanation:
Answer: According to the law of faunal succession, the fossils that are found at the bottom layer are considered to be the oldest, whereas the fossils that are present on the top layer is the youngest.
From the given question, the sable antelope is the youngest, and blue antelope is the oldest. This could suggest that the blue antelopes have undergone evolution and with time, they transformed into the horse, which were found to be present in the middle layer as an evidence. And this animal has further undergone evolution and formed the sable antelopes.
It is a weighted average of the atomic masses of the naturally occurring isotopes of the element.
