(a) Interpretation: Whether the distance covered on throwing a bowling ball change when done on Earth and then on the moon is to be stated. The reason for the same is to be explained. Concept introduction: Mass is the measurement of matter that is present in an object. Weight measures the gravitational force acting on an object. Mass is one of the factors on which gravitational force depends. On changing the gravitational force, weight of a substance also changes, but mass is independent of gravity.
