Gravity and Orbits

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

Why do planets orbit the sun?

Back

Planets orbit the sun because it has more mass, which creates a stronger gravitational pull.

Front

What are the two main elements that make up stars, including our Sun?

Back

Hydrogen and helium.

Front

What does it mean when we say an object has a gravitational field?

Back

It means that the object exerts a gravitational force on other objects with mass around it.

Front

When is the gravitational force between two objects the greatest?

Back

When the masses of both objects are large and the objects are close together.

Front

What is the relationship between mass and gravitational force?

Back

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

Front

What is the role of the sun in our solar system?

Back

The sun is the central star that provides light and heat, and its mass keeps the planets in orbit.

Front

What is an orbit?

Back

An orbit is the curved path that an object takes around a star, planet, or moon due to gravitational forces.

Front

What is the Milky Way?

Back

The Milky Way is the galaxy that contains our solar system, along with billions of other stars.

Front

What happens to the gravitational force as distance increases?

Back

As the distance between two objects increases, the gravitational force between them decreases.
