Energy

Energy is defined as the ability or capacity to perform work or produce change. It exists in various forms, including kinetic energy (the energy of motion), potential energy (stored energy based on an object's position), thermal energy (related to temperature), chemical energy (stored in chemical bonds), electrical energy (associated with electric charges), and nuclear energy (released during nuclear reactions).Energy can be transferred between objects and converted from one form to another, but it cannot be created or destroyed, according to the law of conservation of energy. In practical terms, energy is a fundamental concept in physics and is crucial for understanding how systems work, from simple mechanical systems to complex biological organisms and entire ecosystems. It plays a vital role in everyday life, powering everything from homes and vehicles to industries and technology.The unit of measurement for energy in the International System of Units (SI) is the joule (J), but it can also be expressed in other units such as calories, kilowatt-hours, and electronvolts, depending on the context.
