The Solar System and Gravity

Front

What is the main process that describes the formation of the solar system?

Back

A rotating disk of gas and dust was drawn together by the force of gravity.

Front

What would happen to Earth if the Sun's gravity disappeared?

Back

Earth would stop orbiting the Sun and begin moving in a straight line.

Front

What happens to the gravitational force when the mass of an object increases?

Back

An object with more mass will also have more gravity.

Front

How does distance affect gravitational force between two objects?

Back

Objects with greater distance from each other will have less gravity.

Front

What type of force is responsible for the round shape of celestial objects?

Back

Gravitational force is responsible for giving celestial objects their round shape.

Front

Define gravity.

Back

Gravity is the force that attracts two bodies toward each other, depending on their masses and the distance between them.

Front

What is the role of gravity in the solar system?

Back

Gravity keeps planets in orbit around the Sun and governs the motion of celestial bodies.

Front

How does the mass of the Sun compare to the mass of all the planets combined?

Back

The mass of the Sun is much greater than the mass of all the planets combined.

Front

What is the effect of gravity on the motion of planets?

Back

Gravity causes planets to follow elliptical orbits around the Sun.

Front

What would happen to the Moon if Earth's gravity disappeared?

Back

The Moon would move in a straight line away from Earth.
