How does the mass and weight of the spacecraft on the Moon compare with the mass and weight on Earth? mass on moon weight on moon A same as on Earth same as on Earth B same as on Earth less than on Earth C less than on Earth same as on Earth D less than on Earth less than on Earth 6 A man pushes a heavy box with a weight of 50 N along a rough ground with a force of 30 N. The box moves at constant speed. What is the resultant
