Why is the mass of the bowling ball the same on earth and on the moonbut the weigth of the bowling ball on the earth is different on the moon?

The mass of the Bowling ball remains the same on both Earth and the Moon because mass is a measure of the amount of matter in an object, which does not change regardless of location. However, weight is the force exerted by gravity on an object, which varies depending on the gravitational pull of the celestial body. Since the Moon's gravity is about 1/6th that of Earth's, the weight of the bowling ball is significantly less on the Moon than on Earth.
