What is gravity?

Back

Gravity is the force that attracts two bodies toward each other, such as the force that keeps planets in orbit around the Sun.

How does mass affect gravitational pull?

Back

The greater the mass of a celestial body, the stronger its gravitational pull. For example, Jupiter, being the most massive planet, has the greatest gravitational pull in the solar system.

What keeps Io in orbit around Jupiter?

Back

Io maintains a constant orbit around Jupiter due to the gravitational pull from Jupiter, which is much greater than any other forces acting on it.

What is the relationship between the mass of a celestial body and its gravitational pull?

Back

Typically, a celestial body with greater mass exerts a stronger gravitational pull on other bodies.

What is Sir Isaac Newton's first law of motion?

Back

An object will remain in a state of rest or uniform motion in a straight line unless acted upon by an unbalanced force.

Front

What is the unbalanced force that changes the path of Saturn from straight to curved?

Back

The gravitational force between Saturn and the Sun is the unbalanced force that changes Saturn's path from straight to curved.

What is the role of gravitational pull in the solar system?

Back

Gravitational pull keeps planets, moons, and other celestial bodies in orbit around larger bodies, such as stars and planets.

What happens to an object in motion if no unbalanced forces act on it?

Back

If no unbalanced forces act on an object in motion, it will continue to move in a straight line at a constant speed.
