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 –.
m = mass (The SI unit of mass is the kilogram, kg) g = acceleration due to gravity (The SI unit of g is m/s 2 ) w = weight (The SI unit of w is kg m/s 2 or Newton)
MASS & WEIGHT. Mass is a measure of the amount of matter (stuff) in an object. It is measured in kilograms (kg) Weight is a force and it is the pull of gravity acting on an object. It is measured in Newtons. Experiment. Collect a 20N spring balance and a set of 100 g masses. Predict the weight (force of gravity) on 100 g. Record this in the table.

What happens to the mass and what happens to the weight of the liquid in the cup? Remember that evaporation is the process of turning from a liquid into vapour.
Mass is a measure of the amount of matter in an object. Mass is not related to gravity. The mass of an object does not change when it is moved from one place to another. Mass is commonly measured in grams or kilograms. Weight is a measure of the gravitational force between two objects.
