... Do not be confused by the fact that the object is not directly above the origin as it would be if it were a force vector and we were calculating torque. The “lever arm” is still “a” because when the particle IS above the origin, it will be a distance “a” away from the origin and V will be perpendicu ...

... A system of many particles whose mutual distances are all constant is called a rigid body. Namely a rigid body is an object whose shape does not change as a function of time, like a sphere, a cylinder, a dumbbell, etc. Note that whether an object is a rigid body or not may also depend on the motion ...

3.2 The Momentum Principles
... This equation, formulated by Euler, states that the rate of change of momentum is equal to the applied force. It is called the principle of linear momentum, or balance of linear momentum. If there are no forces applied to a system, the total momentum of the system remains constant; the law in this c ...
