A weighty opinion.
mass, it never changes based where you are. and matter too, energy not sure but i doubt it. weight is the only one that changes
No, the weight never changes unless the object is taken to a different gravitational field. The force required to move them changes, but this is only an application of mechanical advantage.
A persons mass never changes. A persons WEIGHT changes according to the amount of gravitational force put on the object. Some 1 on the moon WEIGHS less on the moon but still has the same mass. Mass plays a factor in the weight but a persons mass never changes by where the person is or so I think.
Kilograms are a measure of mass, and since mass never changes, you would be 42 kg on every planet.
a leopard never changes its spots
Yes. Your mass never changes, no matter where you go but your weight can be affected by gravity.
The weight of a body changes when there is a change in the gravitational pull acting on it. This can happen if the body moves to a different location where the gravitational force is different, like going from Earth to the Moon. The weight can also change if the mass of the body changes, as weight is a result of the force of gravity acting on an object's mass.
Weight
The climate never changes
No changes are needed.
It will be 1 kg, since a gram is a measurement of mass, not weight. Mass never changes.
Weight is dependent on gravity, and mass is not.
