Mass of steel cube is 72 kg on earth. If gravity of moon is 1/6 times of earth, what will be the mass of cube on moon? 

Explanation:

Mass:

• It is one of the fundamental quantities in Physics and the most basic property of matter.
• We can define mass as the measure of the amount of matter in a body.
• The SI unit of mass is Kilogram (kg).
• The mass of a body does not change at any time.
• Only for certain extreme cases when a huge amount of energy is given or taken from a body. For example: in a nuclear reaction.
• Mass of the steel cube is 72 kg on earth. If the gravity of the moon is 1/6 times of earth, then the mass of the cube on the moon will also be 72 Kg.

Weight:

• It is the measure of the force of gravity acting on a body.
• The formula for weight is given by: W = mg
• Mass of the steel cube is 72 kg on earth. If the gravity of the moon is 1/6 times of earth, then the weight of the cube on the moon will also be one-sixth times that on earth.
