A dynamical equilibrium is equil [equilibrium] in bodies in motion.
Mechanics is the science of motion. Statics is the science of equilibrium. Dynamics treats of the motion when the various forces produce with all of their modifications and results, velocity is the rate at which a body moves.
A force of pressure is measured by the force required to remove it. A constant moving force is measured by its momentum. Work is that part of force which is consumed in overcoming resistances.
[ ] is the power which a body in motion [hopes] of overcoming resistances before coming to rest and is measured by the amount of work it can do
A force is completely given when we give the direction [point of application] intensity and time exerted
