Match the Scientist in the Second Column with Their Major

question 30

Short Answer

Match the scientist in the second column with their major astronomical discoveries in the first column. Some scientists will have more than one discovery to their name!
A)Nicolaus Copernicus
B)Johannes Kepler
C)Sir Isaac Newton
D)Galileo Galilei
E)Tycho Brahe
-1)Planets are circular disks rather than just points of light
2)Stellar parallax should show if Earth shifts position over time.
3)Every body in the universe attracts every other body with a force that is directly proportional to their masses and inversely proportional to the square of the distance between them: the first formulation of the law of universal gravitation.
4)The Sun is at the center of the solar system, and Earth is just another planet.
5)The orbits of the planets are elliptical, and the speed of motion changes when the planets are closer to the Sun (faster)or further away (slower).
6)Jupiter has at least four satellites.
7)Venus exhibits phases just like the Moon does. Furthermore, Venus appears smallest when it is in full phase and thus is farthest from Earth.
8)The Moon's surface is not a smooth glass sphere.
9)The Sun has sunspots; dark regions caused by slightly lower temperatures.
10)The first law of motion is inertia, the natural tendency for a moving object that is unaffected by an outside force is to continue moving at a uniform speed and in a straight line.
