Question

Sum of potential energy and kinetic energy is called_________.

Answer 1

Hint: This energy describes the energy of an object because of its motion or position, or both. It is constant in a system which has only gravitational forces or in an otherwise idealized system- that's one lacking.

Complete answer:
- The sum of kinetic and potential energy is known as mechanical energy. An object's mechanical energy can be the result of its motion ( i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy).
- Basically, the total amount of mechanical energy is merely referred to as the sum of the potential energy as well as the kinetic energy.
- Kinetic energy is defined as the energy gained by a body while it is in motion.
- Kinetic energy is gained due to the motion of an object and potential energy is gained due to the height and elastic potential of an object.
- Potential energy is defined as the energy gained by a body based on its position, arrangement and state of object. Potential energy can further be divided into two parts: gravitational potential energy and elastic potential energy.

Note: In general, energy is referred to as the ability to do work. There is a universal law that states "energy can neither be created nor be destroyed". It is further divided into various forms such as potential, kinetic, thermal, electrical, chemical, nuclear, and many more. Energy can be converted and transformed into other forms for example when water is poured from a dam and potential energy is converted into electrical energy by generators.
