University Physics Q&A
Physics - (CORRECT ANSWER)The study of matter and motion.
Natural philosophy - (CORRECT ANSWER)An attempt to explain the behavior of the
universe through philosophical speculation; body of knowledge accumulated since
ancient times.
Scientific method - (CORRECT ANSWER)Iterative process for going from
observations to validated theories.
The Scientific Method Steps - (CORRECT ANSWER)1. Observation
2. Induce- start to ask questions; why?
3. Hypothesis
4. Deduce- Try to explain why
5. Prediction- Guess what is going yo occur
6. Test- perform the experiment and test your hypothesis
Hypothesis - (CORRECT ANSWER)A tentative explanation of an observed
phenomenon.
Law - (CORRECT ANSWER)Tells what happens under certain circumstances;
expressed in the form of relationships between observed quantities.
Theory - (CORRECT ANSWER)A thoroughly tested explanation of a natural
phenomenon, one that can be verified by experiments.
Science is always changing - (CORRECT ANSWER)Laws and theories are tentative
Model - (CORRECT ANSWER)A simplified conceptual representation of some
phenomenon.
Hidden assumptions - (CORRECT ANSWER)Assumptions made without being
aware.
How to address if your observations made do not match your hypothesis -
(CORRECT ANSWER)1. Rerun the test to see if it is reproducible
2. Revise the hypothesis, rethink the assumptions that went into it
3. Reexamine the original observation that led to the hypothesis.
Symmetry - (CORRECT ANSWER)An objects exhibits symmetry when certain
operations can be performed on it without changing its appearance.
Rotational symmetry - (CORRECT ANSWER)If you can rotate an object less than
360 degrees and the object looks like it did before you turned it, then the object has
rotational symmetry.
Reflective symmetry - (CORRECT ANSWER)When one half of an object is the
mirror image of the other half
