In a typical machine with large components, the pressure cannot be “hidden” from human eyes. But in some cases, the pressure can be hidden. For example, in an electromagnetic system, energy can be transferred to an electromagnetic field, which is invisible to human eyes in most cases. Therefore, the pressure can be “hidden” in the electromagnetic field. Let’s take a closer look at this topic.
The whole separate process complies with energy conservation law which, if no energy is exported or incorporated into the system, its full capacity will remain unchanged over time. For example, consider two pucks that slide along the ice. If you summarize the kinetic (motional) power of both packets before the collision, you will find that it is equal to the sum of the force of both packets after their collision. We can actually use energy savings and other information to predict what will happen in such a simple collision.
