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 a natural satellite?

Back

A natural satellite is a celestial body that orbits a planet, such as a moon.

Front

How does the gravitational force change with distance?

Back

The gravitational force decreases as the distance between two objects increases.

Front

What is the average speed of Earth as it orbits the Sun?

Back

The Earth moves around the Sun at an average speed of about 30 km/s.

Front

Which planet has the most moons?

Back

As of now, Saturn has the most moons in the solar system.

Front

What is the difference between a planet and a moon?

Back

A planet is a celestial body that orbits a star, while a moon is a natural satellite that orbits a planet.

Front

Why is Neptune hard to see from Earth?

Back

Neptune is very dim and similar in appearance to the stars, making it hard to see.

Front

What is the gravitational force on an object from Earth compared to other forces?

Back

The gravitational force on an object from Earth is generally stronger than the forces from smaller objects, like a baseball from a person's hand.

Front

What is the role of gravity in the solar system?

Back

Gravity keeps planets in orbit around the Sun and moons in orbit around their planets.

Front

What is the relationship between mass and gravity?

Back

The greater the mass of an object, the stronger its gravitational pull.
