If mass of a body is M on the earth surface, then the mass of the same body on the moon surface is
The Moon’s surface is rocky and covered with craters, regolith (a layer of loose dust and debris), mountains, and plains called maria, formed by ancient volcanic activity. It lacks an atmosphere, resulting in extreme temperatures and no weathering.

The mass of a body is a fundamental property that remains constant regardless of its location in the universe. Mass measures the amount of matter in an object and does not change whether the object is on Earth, in space, or on another celestial body. This constancy is crucial in physics, as it allows for the application of various principles and laws, such as Newton’s laws of motion.
Even when the body experiences different gravitational forces in different environments—like the Moon or Mars—the mass remains unchanged. For instance, a person weighing 70 kilograms on Earth would still have a mass of 70 kilograms in space, even though their weight would vary due to differing gravitational forces.
Moreover, the concept of mass is distinct from weight, which is the force exerted on an object due to gravity. As such, while weight can fluctuate based on gravitational influence, mass remains an intrinsic property.
This consistency allows scientists and engineers to make accurate calculations and predictions about the behavior of objects in various physical scenarios. Understanding that mass remains constant everywhere is fundamental in fields ranging from astrophysics to engineering, influencing how we approach problems related to force, motion, and energy.
