Weight, Mass, & Volume Fluids

Weight, Mass, & Volume � Sing-Along with Mr. Edwards - Mass vs Weight Song Weight � The force of gravity acting on an object. � Weight will change depending on where it is measured (Earth vs. Moon) � Measured in Newtons (N) Mass � The amount of matter that makes up an object or substance. � Your mass would not change on Earth or the Moon. � Measured in units such as grams (g) and kilograms (kg).

Weight, Mass, & Volume � Which has a greater mass: a kilogram of gold or a kilogram of polystyrene foam? Since mass measures the amount of matter in a substance, their mass is the same (1 kg). However, you need a lot more foam than gold to make up a kilogram. Therefore, although the mass is the same, the volume (amount) of foam will be greater.

Weight, Mass, & Volume The amount of space an object or substance takes up. � Measured in cubic units (m³, cm³ etc. ), with liquids measured in m. L/L. � There are two ways to calculate volume: � Regular Object – Use the formula (Volume = length x width x height) Irregular Object – Use the process of displacement (measuring the increased water levels). ▪ Video - Volume of an Irregular Object (Displacement) ▪ Video - Displacement Demo Kid

Comparing Mass & Volume Experiment � Experiment: Comparing Mass & Volume Lab � G 0 al of experiment is to see if there is a relationship between the mass and volume of a substance. To do this, you will be measuring the mass and volume of different liquids and solids. You will then divide the mass by the volume to find the mass of the liquid/solid for 1 unit of its volume.
