The Solar System and Gravity

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards 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 celestial bodies like planets, moons, and stars in their orbits and gives them their round shape.

Front

What is gravitational pull?

Back

Gravitational pull is the force of attraction between two objects due to their masses, such as between the Earth and the Sun.

Front

Why do planets revolve around the Sun?

Back

Planets revolve around the Sun because it has the most gravitational force in the Solar System.

Front

What happens to Earth if the Sun's gravity disappears?

Back

If the Sun's gravity disappeared, Earth would stop orbiting the Sun and begin moving in a straight line.

Front

How does mass affect gravity?

Back

An object with more mass will have more gravity, meaning it will exert a stronger gravitational pull.

Front

What is the relationship between distance and gravity?

Back

The force of gravity decreases as the distance between two objects increases.

Front

What keeps the Moon in orbit around the Earth?

Back

The gravitational pull between the Earth and the Moon keeps the Moon in orbit.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force of gravity acting on that mass.

Front

What is the gravitational force between the Earth and the Moon called?

Back

The gravitational force between the Earth and the Moon is called gravitational pull.
