Work energy and power formula are fundamental concepts in physics that help us understand and describe the motion and interactions of objects in the physical world. They are crucial in various scientific and engineering applications and are interconnected in various ways.
Example:
Lifting a box from the ground to a shelf. When you apply a force to lift the box, you do work on it by transferring energy, increasing its potential energy as it moves upward. Also Check - Unit, Dimension and Vector FormulaExample:
an amusement ride at the summit of a hill. It now possesses the highest possible potential energy and the lowest possible kinetic energy. Potential energy changes into kinetic energy as it makes its way down the slope, giving it speed and excitement.Download PDF Work Energy and Power Formula

2.Potential Energy (PE): The potential energy of an object depends on its position relative to a reference point and is stored energy. PE = m g h where: PE = Potential Energy m = mass of the object g = acceleration due to gravity. 3.Gravitational Potential Energy: The equation for gravitational potential energy is: GPE = m⋅g⋅h Where, m is the mass in kilograms g is the acceleration due to gravity (9.8 on earth) h is the height above the ground in metres 4.Thermal Energy: The thermal energy of an object is related to its temperature and depends on its specific heat capacity. Q = m c ΔT where: Q = Thermal Energy m = mass of the object c = specific heat capacity of the material ΔT = change in temperature 5.Electrical Energy: E = V Q where: E = Electrical Energy ,V = voltage or potential difference Q = electric charge 6.Chemical Energy: The chemical energy in a substance is related to its chemical composition and can be released through chemical reactions. Formula: It varies depending on the specific chemical reaction or process. 7.Nuclear Energy: The energy released during nuclear reactions, such as nuclear fission or fusion, involves the conversion of mass into energy according to Einstein's famous equation. E = Δmc 2 where: E = Energy released m = mass lost during the reaction c = speed of light.
