Explanation:
For starters, energy is what is used to perform tasks. Animals must eat in order to survive, which allows them to refuel after using energy to do their daily activities. But energy is a weird thing. For instance, the binding energy that binds the atomic particles together makes up the majority of a particle or molecule's "mass," which is likewise unknown. True mass, which we don't truly understand, makes up a very small portion of a particle's total mass. Aside from that, mass might be defined as an object's resistance to being moved or its need to come to a halt when moving. Consider a freight train Undoubtedly a large thing. A freight train is so enormous that you could never stop it on your own, even if it were moving at a speed of half a mile per hour. If it is stopped, you also cannot push on it to make it move. This quality is known as inertia. In reality, there are two types of inertia: that resulting from gravitational mass (the "weight" of a freight train) and that a thing always possesses even when not in a gravitational field. Because it is formed of more stuff than, say, the moon, the earth has a bigger interstellar mass. The moon would be more easily moved or halted if being pushed about compared to the earth since it has less inertial mass due to its composition, which is less matter than the planet. Every regular substance has mass. Yet again, mass is mostly composed of the energy that binds things together (electromagnetic force). The actual nature of mass and energy is unknown to us. However, we are aware that, given enough time, the energy of two neighboring systems in contact will tend to equalize, with one system losing heat (due to molecular motion) while the other maintains its temperature. Entropy is what defines "the arrow of time" since, for example, an egg will never fall off a table in the other direction. Entropy is the disorder that creeps into everything unless energy is added to the system, like you arranging your sock drawer — you must expend energy, and later, steal energy from your metabolism digesting food to replenish the energy you spent in arranging the sock drawer. Time therefore always progresses from more ordered to less ordered systems, with the exception of times when the special process known as "life" utilizes energy to restore order that has been lost to entropy. This is perplexing. I know. You have to get used to it. Many individuals would claim that the sun is the source of all energy. That is untrue. While the sun provides the majority of the energy needed for life on earth and to impact the surface, the earth's core is molten for a variety of reasons, such as radioactive, heavy materials that moved downward around the core roughly 4.5 billion years ago. The heat from the magma deep below the earth, not the sun, is what powers the "black smokers" in the deep ocean. The further you dig into the earth, as with a mine, the hotter the ambient temperature. Not all energy ultimately comes from the sun. Another process heats the inside of the earth. Even gravity pushing and pulling on a moon can cause heat through friction, another place where energy comes from. These are sophisticated topics that I cannot due justice here. Look in a physics text book for more info.
