In other words, we are free to choose any vertical level as the location where h = 0 h=0 h = 0 h, equals, 0.For simple mechanics problems, a convenient zero point would be at the floor of the laboratory or at the surface of a table. conan challenges

"WitrynaPotential energy is the stored energy in any object or system by virtue of its position or arrangement of parts. However, it isn’t affected by the environment outside of the object or system, such as air or height. On the other hand, kinetic energy is the energy of an object or a system’s particles in motion.
