Parkinson's disease is a progressive nervous system disorder that can cause tremors in the hands and arms, rigid muscles and speech changes such as slurring, according to the Mayo Clinic. â
Electric power law: P = V x I   P = power in watts   Einstein's law: E â¦ = m x cÂ²   E = energy in joules, m = mass in kilograms, and c is the speed of light.
The formula for calculating Potential energy is P.E. = m * g * h, where 'm' is the mass of an object, 'g' is the acceleration of gravity, 'h' is the height of the object. 1  Stored mechanical energy: The energy which is possessed by an object due to its stored energy of position. 2  E.g., rubber bands, springs. 3  Nuclear energy: Energy locked in the nucleus of the atom.
