"The ball weights about one sixth as much on the moon, and lifting the ball on the moon requires one sixth of the force. However, because the mass of the ball is the same on the moon as on the earth, throwing the ball horizontally at a specified speed requires the same force on the moon as on Earth." On the moon, what if we were to throw the ball downwards, would that require more force? I'm confused when they say it requires the same amount of force to throw ball horizontally on moon. The weight of the object is LESS on the moon. Therefore, the object would seem lighter. So, isn't it true that you can probably throw a lighter object a distance with less force than throwing a heavy object same distance?
