Derivation of Force Newton’s second law of motion states that the rate of change of a body’s linear momentum is directly proportional to the external force and in the direction of the force. When a greater force is applied, the linear momentum changes faster. Consider a body with mass m...

As an equation, this can be written as p=mv, where p represents the momentum. Since an object's velocity can change, the momentum of the object can change. The Law of Conservation of Momentum is useful in describing the momentum of a system of objects. In its simplest terms, the Law ...
force, inmechanics, anyactionthat tends to maintain or alter themotionof a body or to distort it. Theconceptof force is commonly explained in terms ofIsaac Newton’s threelaws of motionset forth in hisPrincipia Mathematica(1687). According toNewton’s first principle, a body that is at rest...

On-balance volume and theaccumulation/distribution lineare similar in that they are both momentum indicators that use volume to predict the movement of “smart money”. However, this is where the similarities end. In the case of on-balance volume, it is calculated by summing the volume on an...
