Module 2 The Universe Review

Within the solar system, planets orbit the sun. What causes planets to orbit the Sun rather than the Sun to orbit the planets?

• The planets have a smaller diameter than the sun.

• The sun has a greater mass than the planets.

• The sun is the center of the solar system.

• The sun is the center of the universe.

0. Noah is investigating the orbit of comets. After gathering data, he claims that a comet travels at a faster speed when it is closer to the Sun. Does Noah’s claim agree with the Law of Universal Gravitation?

• No, because gravity only accelerates objects

• Yes, because the force of gravity is strongest when objects are close.

• No, because objects with more mass experience more gravity, and comets lose mass close to the Sun

• Yes, because the comet will no longer be affected by the gravity of larger planets farther from the Sun.

The distance from Earth to the North Star is about 430 light-years. Which statement describes why scientists use the light-year unit to measure distances in space?

• A light-year unit is very small and distances in space are very small.

• A light-year unit is very small and distances in space are very large

• A light year unit is very large and distances in space are very small.

• A light-year unit is very large and distances in space are very large.

Models serve an important function. Why are scientific models important?

• They allow scientists to study systems that are too small, too large, too dangerous, or too complex to be observed directly.

• They make it more difficult for scientists to understand how systems work

• They prove scientific theories

• They never change.

. Devin decides to model sunlight warming the Northern Hemisphere of Earth during the summer. He uses a globe to model Earth and a spherical lamp to model the Sun. Which model would be the most accurate?

• Devin tilts the North Pole slightly toward the lamp.

• Devin tilts the North Pole slightly away from the lamp.

• Devin points the North Pole straight up so the lamp shines on the equator.

• Devin points the North Pole toward the lamp so it shines directly on the pole.

During a solar eclipse, the Moon passes directly between the Sun and Earth. What effect does the Moon's position have when viewed from Earth?

• The Sun appears larger when viewed from Earth.

• The Moon appears orange when viewed from Earth.

• The Sun's light is blocked when viewed from Earth.

• The Moon's light is blocked when viewed from Earth.

. Sir Isaac Newton reasoned that the force that keeps planets in their orbits around the Sun is due to two factors, one of which is the distance between the planet and the Sun. Which law was the result of his observations and calculations?

• the Law of Superposition

• the Law of Universal Gravitation

• the Law of Conservation of Mass

• the Law of Conservation of Energy
