In Newtonian mechanics, momentum (pl.: momenta or momentums; more specifically linear momentum or translational momentum) is the product of the mass and velocity of an object. It is a vector quantity, possessing a magnitude and a direction.
angular momentum. Also (rarely) moment of momentum or rotational momentum. The rotational equivalent of linear momentum. It is an important quantity in physics because it is a conserved quantity–that is, the total angular momentum of a closed system remains constant. angular velocity (ω)
A snowball effect [1] is a process that starts from an initial state of small significance and builds upon itself (an exacerbating feedback), becoming larger (graver, more serious), and also perhaps potentially more dangerous or disastrous (a vicious circle), though it might be beneficial instead (a virtuous circle).
The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...

The angular momentum J is the sum of an orbital angular momentum L and a spin S. The relationship between orbital angular momentum L, the position operator r and the linear momentum (orbit part) p is = so L's component in the direction of p is zero. Thus, helicity is just the projection of the spin onto the direction of linear momentum.
