Total energy in a system is the sum of all forms of energy present, including kinetic, potential, thermal, and others, and remains constant in a closed system according to the law of conservation of energy. This principle is fundamental in physics and engineering, enabling the analysis of energy transformations and transfers within systems.

forms of energy

Kinetic energy is the energy possessed by an object due to its motion, and it is directly proportional to the mass of the object and the square of its velocity. This form of energy is a fundamental concept in physics, playing a crucial role in understanding the dynamics of systems and the conservation of energy principle.

Kinetic Energy

Potential energy is the stored energy of an object due to its position or state, which can be converted into kinetic energy or work. It is a fundamental concept in physics that helps explain the energy transformations in various systems, such as gravitational, elastic, and chemical systems.

Potential Energy

Thermal energy is the internal energy present in a system due to the random motions of its particles, often associated with temperature and heat transfer. It plays a crucial role in thermodynamics, influencing how energy is transferred and transformed in physical processes.

Thermal Energy

The law of conservation of energy states that energy cannot be created or destroyed, only transformed or transferred from one form to another. This principle is fundamental in physics and ensures that the total energy in an isolated system remains constant over time.

Energy transfers

A closed system is a physical system that does not exchange matter with its surroundings but can exchange energy. It is often used in thermodynamics to simplify the analysis of energy transformations by focusing on energy exchanges only.
