What is total energy in physics? - Quora
the total energy will be exactly the same at a later time. The big yet simple equation you will always write at the beginning of any energy problem is that the total energy at one time will equal the total energy at some later time, or, TE = TE’. Next, plug in the initial and final values of PE and KE and solve.

General Energy Equation: Total Energy = PE + KE = mgh + Potential Energy Equation-from general energy equation can derive potential energy equation-PE = m g h where mass is in kilograms, g = 9.80 m/s2, and h = height above reference level-reference level - where h = 0-valid only if value of g = 9.80 m/s2 and constant

This is the energy of motion. When a system is moving, it has kinetic energy. Thus the object’s motion can be transformed into work. All this means is that a moving object can hit something and make it move, thus accomplishing work. The unit for kinetic energy is the joule. The equation for kinetic energy is:

The left hand side (l.h.s.) must be the total energy operator, , since for a free particle, the total energy is the kinetic energy. c. Conservative forces. For a conservative force acting on a particle, , where V(x,t) is the potential energy function. We’ll just add it to the kinetic energy operator on the r.h.s. of the wave equation.

Alternatively, differentiate the total energy equation where the quantity is the negative of the tangential component of the external force, , that is tangential to the curve, C. As an example, revisit the simple pendulum.

The total energy at one instant in time = the total energy at any other instant in time. Usually these two times are final and initial, but the law applies to any two times. That might not look like an equation, so what you have to do is (1) identify all the different kinds of energy you might have: Kinetic energy (½ mv2)

Total energy should always remain constant during the skater’s run, energy may change between different forms (Kinetic, Gravitational Potential, Thermal). In physics, we say that “energy is conserved”, meaning it cannot be created or destroyed, but can only change forms or move from one object to another.

Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential plus kinetic energies) remains constant as long as the only forces acting are conservative forces.
