SOLAR SYSTEM

Detailed explanation-1: -The amount of matter that a physical body contains is known as the mass of the body. It is the same everywhere in the universe and does not change with the location of the object. The mass of an object can never be zero as an object always contains matter and mass is a measure of matter.

Detailed explanation-2: -Mass always stays the same, but weight can change depending on how much gravity is acting upon an object. Cool fact: Any two masses have a gravitational attraction for one another, and the greater the mass, the greater the pull.

Detailed explanation-3: -The amount of energy/matter in the universe is constant and derives from the mysterious big bang. Over time, this becomes more and more spread out and less and less useful, even though the actual amount doesn’t change.

Detailed explanation-4: -The mass is constant whereas the weight varies from place to place.
