15. The Apollo spacecraft traveled from the Earth to the Moon usingA) A really big slingshotB) The heat from the engine that created a vacuum that pulled the rocket forwardC) The repulsion by the Earth's magnetic forceD) The Sun's gravitational pull to get thereE) The reaction the rocket experience from expelling gases16. GalileoA) Was not the first person to observe the moons of Jupiter.B) Did not accurately define the concepts of velocity and acceleration.C) Was not the first person to turn the telescope onto the heavens.D) Did not conceive the first pendulum clock.E) Did not support the idea of a perfect and unchanging heavens beyond the moon.17. The number 10 7 equalsA) None of the choices presentedB) 10000000C) 0.0000001D) 107E) 0.00118. Ptolemy is famous becauseA) He developed a calendar which is used today throughout the world.B) He determined that the sun is at the center of the solar system (though thisdiscovery was lost during the Middle ages).C) He perfected the epicyclical model of the solar system with the Earth at the center.D) He perfected the epicyclical model of the solar system with the Sun at the center.E) He translated the work of other Greek scientists into Latin.19. While a train is moving at 1 m/s in a straight line, the conductor throws his key-ringtowards the back of the train; the speed of the key-ring, as measured inside the train, isalso 1 m/s. As seen form the platform the speed of the key-ring (ignore the effects ofgravity on the key-ring)A) Cannot be determinedB) Equals 1 m/sC) Would be infiniteD) Equals 2 m/sE) Equals 0 m/sPage 4
20. The scientific method is based onA) The validation of hypotheses based on their underlying philosophyB) The verification of hypothesis using experimentation and observationC) Consensus obtained through voting by the scientific communityD) Majority ruleE) The verification of hypotheses using argumentation21. One of Kepler's laws of motion of the planets isA) All planets move around the earthB) The moon does not spin on it axisC) All planets fall towards the sunD) All planets move in ellipses around the sunE) All planets move away from the sun22. In inertial frame of reference it is observed thatA) Bodies are affected by gravity independently of their massB) Bodies not affected by forces move at constant speed in a straight lineC) Heavier bodies fall faster than light ones.D) Bodies do not move at all.E) Bodies not affected by forces move at constant acceleration in a straight line.23. Two observers perform identical experiments in two spaceships moving at constantspeed (in a straight line) with respect to one another; the ships are far away from allstellar systems. Their results willA) Be almost the same, a small discrepancy occurs when they move at right-angleswith respect to one anotherB) Be identicalC) Be differentD) Cannot be compared because the ships are always far from each otherE) Be identical even if one ship accelerates24. William of Ockham stated that “entities should not be needlessly multiplied'”; by this hemeantA) Spirits rule the natural worldB) All entities are subjective.C) Birth control should be institutionalized.D) The best theory is as complicated as possible.E) The simplest explanation (the one with the least number of assumptions) is thepreferred one.Page 5
