PHYS 1010 Final Exam Questions With
Certified Answers
/. Proportional reasoning - Answer-use letters to represent the shadow, distance, pillar
and radius. can be expressed by showing how one thing is related to another by saying
"a is to b" and "c is to d"
/.uncertainty in measuring - Answer-creates uncertainty in our final measurement
/.Steps of the Scientific Method - Answer-1. choose a question
2. form a hypothesis
3. predict consequences
4. do experiment
5. analyze the results
6. is the hypothesis confirmed or denied?
/.fact - Answer-a close agreement by competent observers who make a series of
observations about the same phenominon.
/.hypothesis - Answer-an educated guess that is only presumed to be factual until
supported by an experiment
/.law/principle - Answer-a hypothesis that has been tested repeatedly and has not been
contradicted.
/.theory - Answer-a synthesis of a large body of information that encompasses well-
tested and verified hypotheses about certain aspects of the natural world
/.Excommunication - Answer-the penalty for scientific fraud in the science community
/.What is the time where science boomed? - Answer-1600-2000
/.Gallileo's inclined planes - Answer-forces acting when moving an object up or down.
there is friction. the speed changes when the object is going up, down or flat.
/.force - Answer-a push or pull on an object
/.net force - Answer-combined effect of several pushes/pulls on an object
/.vector quantity - Answer-quantity whose description requires both magnitude (how
much) and direction (which way). force, velocity, and acceleration
/.scalar quantity - Answer-has a magnitude only. volume, speed, distance
