What is the mass of a bowling ballthe same on earth and the moon?

The mass of a Bowling ball remains the same on both Earth and the Moon because mass is a measure of the amount of matter in an object and does not change with location. However, its weight would differ due to the varying gravitational forces; a bowling ball weighs less on the Moon than on Earth. Specifically, the Moon's gravity is about 1/6th that of Earth's, so while the mass stays constant, the weight decreases significantly.
