Solar System & Gravity Test Review

How does gravity affect the orbit of planets around the sun?

• It pushes the planets away from the sun

• It has no effect on the orbits of planets

• It pulls the planets towards the sun, keeping them in orbit

• It causes the planets to orbit in a straight line

Which of the following best describes the mass distribution in our solar system?

• The mass is evenly distributed among all planets

• The majority of the mass is concentrated in the asteroid belt

• Most of the solar system's mass is in the sun

• The outer planets hold most of the mass

What effect does the mass of a planet have on its gravitational pull?

• The greater the mass, the weaker the gravitational pull

• The mass of a planet has no effect on its gravitational pull

• The greater the mass, the stronger the gravitational pull

• Only the mass of the sun affects gravitational pull

The objects in the solar system formed from spinning dust and gas that began to clump together. Why did the 'clumps' continually get larger?

• Gravity decreased which allowed them to clump together more.

• The speed of the spinning changed which made the clumps larger.

• The electrons bonded.

• As the mass got larger, the gravitational force got larger.

The farther a planet is from the sun, the

• less time it will take to revolve around the sun

• more time it will take to revolve around the sun

• distance does not play a role

• Magnetism

• Gravity

• Friction

• Electricity

How is gravity affected by mass?

• the larger the mass of the object, the greater the gravity
• small objects have no gravity
• gravity is not affected by mass of objects, whether large or small

• The mass of the second object

• The color of the objects

• The distance between the two objects
