Gravity

• The Sun’s gravity pulls them into curved paths, or orbits

• Their own gravity pulls them toward the center of the galaxy

• The Sun’s magnetic field pushes them in circles

• Gravity from other planets keeps them from moving straight

• Earth would stop moving

• Earth would move in a straight line into space

• Earth would move closer to the Sun

• Earth would move in a straight line into space

• Because they are moving too slowly to leave

• Because the larger object’s gravity pulls them into a continuous orbit

• Because magnetic forces hold them in place

• Because space has no gravity

• The gravity of the Sun only

• The gravity of the Moon only

• The gravity of both the Sun and the Moon

• Earth’s rotation only

• Gravity increases as objects get farther apart

• Gravity decreases as objects get closer

• Gravity decreases as objects get farther apart

• Distance has no effect on gravity

• Earth's gravity pulls the Moon toward it

• The Sun’s gravity pushes the Moon toward Earth

• The Moon’s speed keeps it moving in circles

• The lack of air in space holds the Moon in orbit

• They are held by the Sun’s magnetic field

• The Sun has the strongest gravity in the solar system

• The Sun is the only star with enough light

• The planets are attracted to the Sun’s warmth
