Weight and mass are NOT the same. (a) is the measure of the gravitational pull on an object and (b) is a measure of how much an object is made up of. Mass is measured using a (c) and weight is measured using a (d) . The metric units for measuring mass are (e) and the metric units for measuring weight are Newtons.

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?
