Solar System Gravity

Why a ball falls to the ground?

• Earth's force of gravity is GREATER than the ball's, so the ball gets attracted to the ground. 
• Earth's force of gravity is LESS than the ball's, so the ball gets attracted to the ground.

A person would weigh less on on the Moon than on the Earth because . . .

• Moon has more mass, and therefore more gravity
• Moon has less mass, and therefore more gravity
• Moon has more mass, and therefore less gravity
• Moon has less mass and therefore less gravity
