300

Which is an example of gravity?

What happens to light as you move farther away from its source?

The light becomes less intense/dimmer.

400

How do you know that something has gravity? Give an example.

Objects with gravity attract other objects. For example, Earth's gravity pulls a dropped ball toward the ground.

400

What causes shadows?

An object blocks light from reaching a surface.

400

What is the difference between rotation and revolution?

Rotation is when an object spins on its axis. Revolution is when an object moves around another object.
