PHY 150 - Exam 1 | UPDATED Questions with 100%
Verified Answers
Q1: What is Physics?
A: describing the interactions of energy, matter, space, and time, and what fundamental
mechanisms underlie every phenomenon.
Q2: What is a model?
A: representation of something that is often too difficult to display directly.
Q3: What is a theory?
A: an explanation for patterns in nature that is supported by scientific evidence and verified
multiple times by various groups of researchers.
Q4: What is a law?
A: uses concise language to describe a generalized pattern in nature that is supported by
scientific evidence and repeated experiments.
Q5: What is the difference between a law and a theory?
A: A law is a concise statement, and a theory is a broader statement.
Q6: What is the scientific method?
A: A process that begins with an observation and question, followed by research and
hypothesis. They then test the hypothesis via experiments and draw a conclusion.
Q7: What conditions exist under classical physics?
A: 1) Matter must be moving at speeds of less than 1% the speed of light
2) The objects must be large enough to be seen under a microscope
3) Only weak gravitational fields acting on the object
Q8: What are the fundamental SI Units?
A: Meter (m), Kilogram (kg), Second (s), Ampere (A)
Q9: What is Accuracy?
A: how close a measurement is to the correct value for that measurement.
Q10: What is precision?
A: how close the agreement between repeated measurements.
Q11: What is kinematics?
