Physical Science Mass and Weight. Use the following formula to solve for weight: Weight (W) = Mass (m) x gravity (g) W = mg. Mass is measured in kilograms (kg) Gravity on earth is a constant: 9.8 m/s2 Weight is measured in Newton’s (1 N = 1 kg m/s2) Answer the following questions – show ALL WORK and UNITS. 1. Define Mass –.
