Law of conservation of energy

The information on this page is ✔ fact-checked. The law of conservation of energy states that the total energy within an isolated system remains constant. This means that energy cannot be created or destroyed; it can only change from one form to another. For instance, consider a roller coaster ride. As the coaster climbs up … Read more

Mechanical energy

The information on this page is ✔ fact-checked. Mechanical energy refers to the sum of potential energy and kinetic energy possessed by an object or a system. Potential energy is associated with the position or configuration of an object, while kinetic energy is related to its motion. Objects possess mechanical energy when they have the … Read more

Gravitational energy

The information on this page is ✔ fact-checked. Gravitational energy, also known as gravitational potential energy, refers to the energy an object possesses by virtue of its position in a gravitational field. It is directly related to the object’s height above a reference point. The higher the object is positioned, the greater its gravitational potential … Read more

Elastic energy

The information on this page is ✔ fact-checked. Elastic energy refers to the potential energy stored in an object when it is deformed or stretched due to the application of a force. It is produced when an object undergoes elastic deformation, which means it can return to its original shape after the deforming force is … Read more

Light

The information on this page is ✔ fact-checked. Light, associated with electromagnetic radiation within the visible spectrum, emanates from various sources like the Sun, light bulbs, and stars. This luminosity is a result of electrons jumping between different orbits – light is emitted when an electron descends from a higher orbit to a lower one, … Read more
