PHYS 1600 (GUELPH MIDTERM) EXAM WITH
COMPLETE SOLUTIONS
Newton's Law of Gravity - ANSWER Every object attracts every other object with a force
that is proportional to the product of the two masses and inversely proportional to the
square of the distance between them.
orbit - ANSWER The path of an object as it revolves around another object in space
Geocentric - ANSWER explanation of the Sun's apparent motion in which the Sun circles
around the Earth once per year
circumpolar stars - ANSWER stars that can be seen at all times of the year and all times
of night.
How far away is the Moon? - ANSWER 30 earth diameters
Does the earth rotate? - ANSWER Yes, about its north-south polar axis.
When it is noon in Toronto what time is it in Guelph? - ANSWER The same, both cities
are in the same time zone
In 1850 when it was noon in Toronto, what time was it in Guelph? - ANSWER A few
, minutes early, as solar time was used back then
The Earth orbits the Sun in approximately - ANSWER 365¼ days.
Seasons on Earth are caused by - ANSWER The seasons are a result of the tilt of the
Earth's rotation axis relative to the plane of its orbit about the Sun.
Heliocentric - ANSWER Based on the belief that the sun is the center of the universe
asteroid belt - ANSWER the region of the solar system between the orbits of Mars and
Jupiter, where many asteroids are found
True or false, The rotation and revolution of the Earth are in opposite directions. -
ANSWER True
True or False, The plane of the Moon's orbit is tilted at about 5° to the ecliptic plane, -
ANSWER True
The main reason for seasonal effects at mid-latitudes on the Earth is: - ANSWER the tilt
of the spin axis of Earth to its orbital
plane, resulting in a change in the angle of
incidence of solar radiation on the Earth's
surface as the Earth orbits around the Sun.
