Há 4 dias · Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or various other forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. Learn more about energy in this article.
Há 5 dias · Physics portal. Category. v. t. e. Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows:
