Gravity and 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

How does a person's weight on the moon compare to their weight on Earth?

Back

A person weighs less on the moon than they do on Earth due to the moon's weaker gravitational force.

Front

What is the relationship between mass and gravity?

Back

Gravity is the force that objects exert on each other because of their mass.

Front

What is the gravitational force between two objects with greater mass?

Back

The gravitational attraction increases as the mass of either or both objects increases.

Front

What is the effect of gravity on falling objects?

Back

Gravity causes objects to accelerate towards the Earth at approximately 9.8 m/s².

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 planets.

Front

What happens to gravitational force if the distance between two objects doubles?

Back

The gravitational force decreases to one-fourth of its original value.

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.
