SCMH 1010 Final Exam QUESTIONS
AND CORRECT ANSWERS
What is physical science? - CORRECT ANSWER Attempt to understand the workings of the
universe
• Attempt to describe the universe with mathematics
• Attempt to make predictions about the world
around us
• Amoral
• Evolving
Common abuses of science - CORRECT ANSWER • False authority
• Statistical shenanigans
• Politicization of science (adding an agenda)
• The ad hominem attack
Scientific Method - CORRECT ANSWER Observation • Identifying Patterns • Develop a
Hypothesis
• Qualitative • Quantitative • Predict and Test
Ptolemy - CORRECT ANSWER - Egyptian astronomer
- 2nd century AD
- had to make corrections for retrograde motion
- planets surround the Earth
Copernicus' Universe - CORRECT ANSWER - planets surround the Sun
Tycho Brahe - CORRECT ANSWER first modern astronomer
speed - CORRECT ANSWER v=d/t
, velocity - CORRECT ANSWER speed plus direction
acceleration - CORRECT ANSWER rate of change of your velocity aka how fast your velocity
is changing
Galileo - CORRECT ANSWER - invented telescope
supported Copernicus' model
- Showed that objects accelerate at the same rate regardless of their relative masses
gravity - CORRECT ANSWER 9.81 m/s^2
Newton's First Law of Motion - CORRECT ANSWER - aka Law of Inertia
- In the absence of a net external force, an object's state of motion will remain constant
- the property of any object to resist changes in its state of motion
Newton's Second Law of Motion - CORRECT ANSWER F = ma
Newton's Third Law of Motion - CORRECT ANSWER To every action there corresponds an
equal and oppositely directed reaction.
Universal Law of Gravitation - CORRECT ANSWER Isaac Newton
Fg = G m1m2 /d^2
G is the universal gravitation constant
work - CORRECT ANSWER done when force is exerted over a distance
W = fd
