If a plastic ball floats on the surface of water on the earth, will it float or sink if it is placed in a bucket of water on the moon?

Expert Answer:

The plastic ball will float if placed in a bucket of water on Moon. This is because if the ball floats on water on earth means that the ball has mass and experiences an upthrust. The same ball when placed in a bucket of water on Moon will have the same mass but the weight of the ball reduces (W= mg) and experiences an upthrust. Also, upthrust is directly proportional to 'g' and 'g' is less on Moon (1.63 m/s2) so the ball floats.
