7.3: Momentum, Newton’s Second Law and Third Law
2022年7月20日 · Our modern term for quantity of motion is momentum and it is a vector quantity. →p = m→v. where m is the inertial mass and →V is the velocity of the body. Newton’s Second Law states that. Law II: The change of motion is proportional to the motive force impressed, and is made in the direction of the right line in which that force is ...
Newton's Second Law: the Momentum Principle - Physics Book
2022年12月4日 · The Main Idea. Newton's second law of motion, also known as the momentum principle, explains how forces cause the momentum of a system to change over time. The principle states that F → n e t = d p → s y s t e m d t where p → is the Linear Momentum of a system, F → n e t is the external Net Force acting on the system from its ...
