Earth's moon

I am playing soccer on the Earth’s moon. The acceleration due to gravity on the Earth’s moon is a=1.6m/s. When I kick the soccer ball, the ball stays in the air longer than it would on Earth. That is because there is less gravity pulling the soccer ball down to the ground than on Earth. The ball slowly comes back to the ground. When I jump up to head the soccer ball I jump much higher than I would on Earth. I land down to the ground slower. This is caused by the same reason: there is less gravity pulling the soccer ball down to the ground.

Great work. I like how you included yourself in the example. Good observations.
