Read each question carefully and provide your best answer. Show all work for calculations.
1. Which of Kepler's Laws describes that planets sweep out equal areas in equal times?
First Law
Second Law
Third Law
Law of Universal Gravitation
2. The force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers. This is known as:
Kepler's First Law
Kepler's Third Law
Newton's Second Law
Newton's Law of Universal Gravitation
3. According to Kepler's First Law, planets orbit the Sun in paths called , with the Sun at one focus.
4. The period of a planet's orbit squared is proportional to its average distance from the Sun cubed. This is Kepler's Law.
5. Explain the concept of centripetal force and its role in maintaining an object's orbit.
6. Observe the image below depicting planets orbiting the Sun. Identify and label the Sun and at least two planets.
7. A geostationary satellite orbits the Earth once every 24 hours.
True
False
8. The orbital velocity of a satellite increases as it gets closer to the central body.
True
False
