pull, as against a resistance
the act of applying force to propel something

nonturbulent streamline flow in parallel layers (laminae)
The study of forces and the resulting motion of objects through the air.

Action / Reaction
Newton's 3rd Law
a body of matter without definite shape
move with force, "He pushed the table into a corner"
a rate of change of velocity
Newtons 1st Law
(Law of Inertia) an object in motion tends to stay in motion & an object at rest stays at rest unless acted upon by an outside force.
Newtons 2nd Law
(Force) when force is applied to an object it is accelerated in the direction of the force. (mass and force are inversely proportional)
Newtons 3rd Law
For every action there is an equal and opposite reaction
