We all can measure the mass of a body by any common instrument like Spring Balance. But if we go from one place to another place the gravitational force will change, like if we go from 1st floor to 10th floor or from coastal region to plateau region. The gravitational force depend on the height. Is there any way to calculate mass of a body without gravitational force ? Please tell me if i am wrong, i will be thankful to you. If i am not wrong than please answer me.
