Therefore the 3 equations we need are. The potential energy of an object is zero when it is in the movement and kinetic energy is zero when the object is in rest. Using our equation we can determine the kinetic energy of the sphere.
Combining the 2 expressions we get Now we already know that kinetic energy is the energy that it possessed due to its motion.
Definition for kinetic energy based on its charge and the voltage E. F ma equation 1. Therefore we can say that kinetic energy is. Combining the 2 expressions we get Now we already know that kinetic energy is the energy that it possessed due to its motion.
