What is energy in Environmental Studies?

In Environmental Studies, energy is defined by physicists as the capacity to do work. Energy is found on our planet in a variety of forms, some of which are immediately useful to do work (like solar energy), while others require a process of transformation (like fossil fuels). The sun is the primary energy source in our lives.

10.2: Forms of Energy

Energy is the ability to do work. Work is done when a force is applied to an object over a distance. Any moving object has kinetic energy or energy of motion, and it thus can do work. Similarly, work has to be done on an object to change its kinetic energy. The kinetic energy of an object of mass (m) and speed (v) is given by the relation

About Energy definition in environmental science

In science, energy is the ability to do work or heat objects. It is a scalar physical quantity, which means it has magnitude, but no direction. Energy is conserved, which means it can change from one.

The term “energy” comes from the Greek word energeia or from the French words enmeaning in and ergon which means work. The SI unit of energy is the joule (J), w.

One form of energy may be converted into another without violating a law of thermodynamics. Not all.

The various forms of energy are classified as kinetic energy, potential energy, or a mixture of them. Kinetic energy is energy of motion, while potential energyis stored energy or e.

Another broad way of classifying energy is as renewable or non-renewable. Renewable energy is energy that replenishes within a human lifetime. Examples i.
