- Weight and Mass (pages 368-309) 13. What is weight? 14. Write the formula used to calculate the weight of an object. 15. Is the following sentence true or false? Because the weight formula shows that mass and weight are proportional, doubling the mass of an object will not affect its weight. 16. Complete the table below by describing the difference between mass and weight. multicolumn(2)(|c|)( Mass and Weight ) Mass & Weight & 17. On the moon, the acceleration due to gravity is only about one that on Earth. Thus, an object will weigh on the moon than it weighs on Earth.
