Astronomy Unit Test: Spring 2025

Front

Kepler's 2nd Law deals with: the shape of the planets' orbits, the speed/area the planet travels, the length of time it takes the planet to orbit the sun

Back

the speed/area the planet travels

Front

Why do planets orbit the Sun?

Back

The Sun is the most massive object in our solar system, so it exerts the greatest gravitational pull.

Front

What would happen to the planets in the solar system if the sun’s gravitational force were to suddenly disappear?

Back

They will fly away in straight lines.

Front

Why does North Carolina experience a change of seasons from winter to summer?

Back

the tilt of Earth’s axis, and its revolution around the sun

Front

What would happen to your weight if Earth's mass increased 7 times?

Back

increase because gravitational force increases

Front

Why are the seasons opposite in India and Australia?

Back

because Earth is tilted on its axis

Front

What is happening to the gravity of the sun and moon in this tidal example?

Back

the gravity of the sun and moon are competing

Front

Why does the moon's gravitational pull have more of an effect on tides than the sun's gravitational pull?

Back

The moon is closer to the Earth than the sun.

Front

What changes with different gravitational forces?

Back

the weight of an object

Front

What season and time of day is Location Z experiencing?

Back

Winter/Night
