Gravity and the Solar System

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

How does distance affect gravitational force?

Back

The closer two objects are, the stronger the gravitational force between them.

Front

What keeps the moon in orbit around the Earth?

Back

Gravity is the force that keeps the moon in orbit around the Earth.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the balance between gravity and inertia responsible for?

Back

It keeps the planets in orbit around the sun.

Front

What are the outer planets in our solar system?

Back

The outer planets are Jupiter, Saturn, Uranus, and Neptune.

Front

Why do we weigh more on Jupiter than on Earth?

Back

Because Jupiter has more mass, it exerts a stronger gravitational force.

Front

What is mass?

Back

Mass is the amount of matter in an object, which does not change regardless of location.

Front

What is weight?

Back

Weight is the force of gravity acting on an object's mass.

Front

How does the mass of an object affect its gravitational pull?

Back

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