Click hereto get an answer to your question ️ The dimensional formula for potential energy is: . The dimensional formula of electric potential is given by, Since, Potential energy = Charge of particle × Electric potential, Therefore, electric potential =  Potential energy × [Charge of a particle]-1 . Motion occurs when this stored energy is converted into kinetic energy. It has several interpretations and its types vary widely. Potential energy is the dormant stored energy in any system. All macroscopic systems outside the atomic nucleus are either governed by the electromagnetic or gravitational forces. On substituting equation (4) and (5) in equation (3) we get, Potential Energy = [M1 L0 T0] × [M0 L1 T-2] × [Mo L1 T0], Therefore, the dimension of potential energy = [M1 L2 T-2] . The formula is as follows: where m is the mass, g is the acceleration due to gravity (9.8 m/s2) and h is the height above Earth surface. In all forms of life on this earth, energy exists as one dynamic process. The formula for potential energy states that the potential energy stored in an object is directly proportional to the position of an object with respect to a defined 0 point. (2), For acceleration due to gravity, the dimensional formula = [M0 L1 T-2] . . . . plZZZZZ!!! T = dimension of time … All energies have same dimension. Energy is the most fundamental concept in physics. The Lagrangian is the difference of potential and kinetic energy of a system. We'll assume you're ok with this, but you can opt-out if you wish. Well, we're looking for good writers who want to spread the word. function CalculateGPI(){var A=parseFloat(document.getElementById('mass').value);var B=parseFloat(document.getElementById('height').value);x = (A*B*9.8);if (isNaN(x)){alert("Please Enter Mass and Height Values!")} wat's the dimensional formula of potential energy? The formula for potential energy of an object in a force field depends on its position and other inherent factors like mass and charge.

It is a type of energy that a system possesses on account of its configuration and position of various constituents of that system in presence of a force. (1), The dimensional formula of Altitude and Mass = [M0 L1 T0] and [M1 L0 T0] respectively . Whatever be the operating force (electromagnetic, gravitational, strong or weak), every change that occurs in the universe is a conversion from potential to kinetic energy. Favorite Answer. . Potential energy is measured in SI unit of ‘Joule‘. The formula is as follows: Gravitational Potential Energy = mgh where m is the mass, g is the acceleration due to gravity (9.8 m/s2) and h is the height above Earth surface. . ∴ The dimentional formula of electric charge = [I 1 T 1].....
