Dynamics of a mechanical particle
... Newton`s first law: If no net force acts on a body, it will move on a straight line at constant velocity or will stay at rest if it stays initially at rest. Inertial frame of reference: The frame of reference in which Newton`s first law is valid is called inertial frame of reference. Momentum: Produ ...
