Check all the true statements about the Law of Universal Gravitation.
All objects in the universe attract all other objects in the universe.
The force of attraction increases when mass(es) increase.
The force of attraction decreases when the distance between the masses increases.
Gravity can either attract or repel.
Check all that are true about the Earth and the moon.
The Earth's pull on the moon is greater than the moon's pull on the Earth because the Earth is bigger.
Mass on the moon is the same as mass on the Earth.
Weight on the moon is the same as weight on the Earth.
If gravity were to disappear, the moon would fly out into space.

The reason why ocean tides happen is
Electrical forces between the sun and the moon
gravitational forces between the Earth and the moon.
Magnetic forces between the Earth and the moon
Motion of the moon around the earth
The sun is the anchor point of our solar system because of
