Acontainer of rocks with a mass of 65.0 kilograms is brought back from the moon's surface where the acceleration due to gravity is 1.62 meters per second2. what is the weight of the container of rocks on earth's surface?

The mass is an intrinsic property of a substance which means that wherever it is placed, the mass would stay the same. This being said, the mass of the container of rocks in the Earth's surface is still 65 kg. 

To determine the weight of the object on the Earth's surface, we multiply the mass with the acceleration due to gravity, 9.8 m/s². 

           Weight = mg

Substituting with the known values,
   
           Weight = (65 kg)(9.8 m/s²)
            Weight = 637 N

637 N
