SCMH 1010 EXAM 1 VOGEL QUESTIONS
AND ANSWERS GRADED A+ 2026
What is the difference between the Ptolemaic (geocentric) and the Copernican (heliocentric)
systems? What evidence finally, validated the Copernican system? - ANS The Ptolemaic
System:
said the sun and planets rotated around the Earth as the Earth was at the center of the solar
system.
The Copernican system:
is the correct system and what we use today. It states that the sun is at the center of the solar
system and the planets rotate around it. This was proven true when Galileo watched the
position of Venus and how it changed phases throughout the year.
What were the scientific contributions of Tycho Brahe and Johannes Kepler? - ANS The two
were astronomers that developed planetary motion and determined that the planets orbit
around the sun.
What was the scientific contribution of Galileo Galilei? - ANS Galileo created the scientific
method as well as make many advancements towards math and astrology through the use of
the telescope.
What was the scientific contribution of Isaac Newton? - ANS Newton created significant work
towards forces and math, but his greatest accomplishment is the development of the universal
law of gravity.

, Be able to visually identify the graphical, physical, and mathematical relationships between
distance, velocity, and acceleration for falling or descending objects? - ANS Distance = m, cm,
mm
or how far an object has traveled
Velocity = m/s
or the distance an object has traveled within a certain time
Acceleration = m/s2
or the change in velocity within a given time
What is a vector and what are the two components of a vector? - ANS A vector is an object
that has both a magnitude (length) and a direction.
What do the Newtonian laws say about what will happen to an object in motion or an object
not in motion (Newton's 1st Law)? - ANS If a body is at rest or moving at a constant speed in
a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it
is acted upon by a force.
What are the units for force, velocity, and acceleration? - ANS Force = mass x acceleration (N)
Velocity = distance/time (m/s)
Acceleration = change in velocity/change in time (m/s2)
How is momentum different than velocity? How does mass affect inertia? - ANS An external
force is always required to change the velocity, but momentum can be changed by changing
mass.
