Rotation, Revolution and Gravity

Front

What are the two factors affecting the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

When objects are more massive, is the force of gravity between them stronger or weaker?

Back

Stronger.

Front

What causes day and night on Earth?

Back

The rotation of Earth on its axis.

Front

Why would a person weigh less on the Moon than on Earth?

Back

The Moon has less mass and therefore less gravity.

Front

When objects are farther apart, is the force of gravity between them stronger or weaker?

Back

Weaker.

Front

Define rotation in the context of Earth.

Back

Rotation is the spinning of Earth on its axis, which causes day and night.

Front

Define revolution in the context of Earth.

Back

Revolution is the movement of Earth around the Sun, which takes one year.

Front

What is gravity?

Back

Gravity is the force that attracts two bodies towards each other.

Front

How does mass affect gravity?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.

Front

How does distance affect gravity?

Back

The greater the distance between two objects, the weaker the gravitational force between them.
