Physics - Gravitation and Kepler Review

Kepler's First Law states

• objects attract other objects with a force that is directly proportional to the product of their masses

• the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun

• An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.

• Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.

Which of the following lists the scientists in correct chronological order?

• Galileo, Copernicus, Kepler, Brahe

• Copernicus, Galileo, Kepler, Newton

• Kepler, Brahe, Copernicus, Galileo

• Newton, Kepler, Copernicus, Brahe

According to Einstein's Theory of Relativity, which of the most accurately describes time?

• Time is a human construct and is constant

• Time is a human construct and varies depending upon where an object is in space

• Time is relative and varies depending upon how fast an object are traveling

• Time is relative and varies depending upon how fast an object is traveling; the faster an object is traveling the slower time passes

When looking at the Earth's orbit, what can be said about summer and winter in the Northern hemisphere?

• Because of its orbit, Earth is the same distance from the Sun in both the Northern hemisphere's summer and winter seasons.

• Because of its orbit, Earth is further away from the Sun in the Northern hemisphere's winter season and closer during the summer season.

• Because of its orbit, Earth is further away from the Sun in the Northern hemisphere's summer season and closer during the winter season.

• None of the above accurately describe the Earth's orbit.

As an object moves further from the surface of the Earth, what happens to its mass?

• The mass of the object will not vary as it moves further from the surface of the Earth

• The mass of the object will decrease as it moves further from the surface of the Earth.

• The mass of the object will increase as it moves further from the surface of the Earth.
