inertia
willingness of an object at rest or continue motion unless acted upon by an outside source.
acceleration
rate of change and/or speed over a period of time.

rate of movement at any given time.
velocity
quickness or speed of an object at any given time. i.e MPH
Newton's First Law
an object at rest will remain at rest until acted upon by a force. (inertia)
Newton's Second Law
if an object moving with uniform speed is acted upon by an external force, acceleration directly proportional to force and inversely to mass. (force)
Newton's Third Law
for every action there is an equal and opposite reaction.
Bernoulli's Principle
when a constriction is reached, speed increases and pressure decreased.
