Poll

A mechanical scale is like a seesaw. An object of unknown mass is put on one side of the scale, and then weighted tabs are moved on the other side of the fulcrum until the two sides are in balance. Gravity is acting on both sides with the same force. Do you think this measures mass? Or weight?
