Forces, Work, Power
摘要
In this chapter we will discuss the notion of forceForces in an intuitive manner. We shall think of a force \(\textbf{F}\) , acting on the point P, as the vector that characterizes the interaction of P with other bodies, and implicitly agree that forces have an absolute nature, i.e. independent of a frame. We will return to this in Chap. 8, when we discuss the concept starting from the Laws of Mechanics.
