NATS 1530 Lecture Notes - Lecture 5: Plutonium, Liquid Rocket Booster, Solar Sail
Document Summary
Nats1530 f18 space flight and exploration lesson 5 study guide: rocket science. To prepare for the quiz on this lesson, answer the questions below. Suppose that an asteroid with momentum p1 collides into another asteroid with momentum p2, causing both asteroids to break apart into hundreds of fragments. Momentum: is an object"s tendency to move. An object with mass m and speed v has p=mxv. P1=p2: suppose that an astronaut at rest in space throws a tool in the forward direction. In what direction will the astronaut be propelled (ie, forward, backward, left, right, etc. Tells us that forward propulsion leads to propulsion in the opposite direction. Aircraft moves forward when thrust > drag (thrust is the reaction force from the engine"s rearward exhaust) Aircraft rises when lift > weight (lift force arises from horizontal motion through air; increases with speed)
