Sir Isaac Newton () - answerWho stated the three laws of motion explaining jet propulsion? (Reference page 1-4). Daniel Bernoulli () - answerWho explained the principles behind convergent/divergent ducts? (Reference page 1-4). Force - answer____________ is the action of effect on a body that changes the state of motion of the body (p. 1-5). Matter - answer____________ is anything that occupies space and has weight (p. 1-5). Mass - answer____________ is the quantity of matter in a body measured in relation to its inertia. (p. 1-5). Weight - answer____________ is the common measurement to determine the quantity of matter with the pull of gravity on it (p. 1-5). Slug - answerA ____________ is a mass with force and acceleration (due to gravity) taken into consideration (p. 1-5). Energy - answer______________ is the capacity for doing work (p. 1-5). Work - answer_______________ is done when a force moves a mass over a distance (p. 1- 5). Power - answer____________ is the rate of doing work, (p. 1-5). 33,000 - answerHorsepower is the English measurement for mechanical power and is how many foot-pounds per minute? (Reference page 1-5). Speed - answer_____________ is the distance a body in motion travels per unit of time, (p. 1-5). Velocity (V) - answer_____________ is speed in a given direction, (p. 1-5). Acceleration (a) - answer______________ is the gain or loss of velocity with time, (p. 1-5). 32.2 FPS squared - answerHow many feet per second is acceleration due to gravity? (Reference page 1-6). Ram effect - answer_____________is defined simply as more air arriving at the engine intake than the engine can ingest, (p. 1-6). Ram recovery - answer______________ is the airspeed at which ram pressure rise is equal to friction pressure loss, (p. 1-6). First - answerNewton's _________ law states "A body (mass) at rest tends to remain at rest, and a body in motion tends to move at a constant speed, in a straight line unless acted upon by some external force," (p. 1-6). Second - answerNewton's _________ law states "An unbalance of force on a body tends to produce an acceleration in the direction of force, and that acceleration, if any is directly proportional to the force and inversely proportional to the mass of the body," (p. 1-6). Third - answerNewton's _________ law states "force is proportional to the product of mass and acceleration," (p. 1-6). 4 - answerThere are ____ differe
