Role of gravity

the weight of the human body on the moon is about one sixth on the moon however its mass is the same.
watermelons and apples fall at the same rate because only air resistance affects how fast they fall and thereis no atmosphere on the moon.

Gravity on the moon is 16.5% of what it is on earth so a 50 kg person would weigh 8.25 kg on the moon. And the watermelon and the apple fall at the same speed as the shape and size or mass of a body doesn´t matter. They accelerate at the same rate anyway. On earth air resistance is a factor for lighter objects but the apple and the watermelon would fall at the same speed here too. Only they would accelerate faster.

Gravity is an acceleration that acts uniformly on all masses. Your weight is simply your mass multiplied by the force due to gravity, measured in Newtons. I have a mass of about 85kg. On Earth, where the gravitational force is 9.81N/kg, weigh 9.81x85 = 834N. On the Moon the gravity is 1/6th that on Earth, so I would weigh 834/6 = 139N, the same as a 14kg child weighs here on Earth.
Galileo proposed that all objects accelerate at the same rate when dropped, whatever their weight, because the same force acted on all of them. This was demonstrated on Apollo 15, when Dave Scott dropped a hammer and a feather together on the lunar surface. They both hit the ground at exactly the same time. In your example, the same would hold true. Your watermelon and apple will hit the ground together.

You'll weight 1/6th the amount on the moon than you would on the Earth. The watermelon and apple will fall at the same speed on the moon.

Watermelon and apple fall at the exact same rate, whether on the Earth or moon

1. 1/6 of the weight on Earth.
2. Barring any possible air resistance all objects fall at the same speed.

Both the apple and the watermelon will fall at the same speed (Galileo).

1- 1\6 ur weight on earth ..
2- they will fall at the same time cuz there is no air in the moon therefor no air resistance ..

you're weightless on the moon plus both watermelon and apple will float on the moon. on earth it is assumed by the law of gravity that both fruits will land at the same time if you drop them from athe same point.

Everything falls at the same rate.
And your weight on the moon is approximately 1/6th that of your weight on Earth (I think).
