The leftover energy is transformed into kinetic energy after the electrons are brought to the metal surface. hv = + Kmax is the photoelectric formula. Potassium's work function is =2.29eV=2.241.610=19J.
Kinetic energy (KE) can be calculated using the formula KE = 0.5 x mv2. Here, m stands for mass, which is a measure of how much matter is contained within an item, and v for velocity, which is a measure of how quickly the thing changes positions.
To determine the energy shift in a reaction: Energy change is defined as the difference in the bond energies of all the bonds in the reactants and products. This is known as the "energy in" and "energy out" components.
