On earth, a closed box weighs 56.84 n. what would the mass of the box be on the moon?

Answer;

=5.8 kg , same as the mass on the earth's surface

Explanation;

The gravitational force on the earth surface is 9.8 N/kg

Therefore; a box weighing 56.84 N will have a mass of;

= 56.84 /9.8

=5.8 kg

The box weighs 5.8 kg on the earth surface.

On the moon's surface the box would still weigh 5.8 kg , this is because the mass of an object or a substance is constant everywhere.

-Mass of a body is constant or remains the same everywhere irrespective of the gravitational force, unlike the weight which varies depending on the pull of gravity of a place.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
