When an astronaut travels to different planets, which of the following planets will the astronaut’s mass stay constant from what is measured on earth? a)jupiter b) mars c) mercury d) all the different planets

D) All the different planets

Explanation:

The mass of an object is an intrinsec property of the object, that gives a measure of the "amount of matter" contained in the object.

Therefore, the mass of an object (or of a person) does not depend on the location of the object: that means, it remains the same on different planets.

So, the mass of the astronaut will remain the same in all the different planets.

Instead, the weight of an object is given by:

where

m is the mass

g is the acceleration of  gravity

Since the value of g is different on different planets, then the weight of the astronaut will be different on the different planets.

gravititional force is a force that is acting around you, it is non-contactable and it is a force that pulls you to the core of the earth.
