The distance an object travels when thrown is proportional to the square of the initial velocity and inversely proportional to the acceleration due to gravity. So, if we throw an object with the same initial velocity on the Moon as we would on Earth, it would travel about six times farther on the Moon.
In other words, if you can throw a ball 100 meters on Earth, you would be able to throw it about 600 meters on the Moon.
Of course, this assumes that you are able to throw the ball with the same initial velocity on both planets. In reality, it would be difficult to throw the ball with the same force on the Moon because you would weigh only about one-sixth of your weight on Earth.
