-
Volume of a Stone: A stone is placed in a measuring cylinder containing 20cm³ of water. The water level rises to 38cm³. The volume of the stone is 18cm³.
-
Weight of Objects: Four objects with different gravitational field strengths. The object with a mass of 4.5kg in a field strength of 9.0 N/kg has the greatest weight.

-
Weight and Gravitational Field Strength: A spacecraft has zero weight between Earth and Moon because the gravitational fields cancel each other out.
Density of a Liquid, and Mass Determination
-
Density of a Liquid: A measuring cylinder contains a liquid. Measurements before and after the addition of liquid gives the density of liquid in the cylinder.
-
Mass of Air in a Room: The mass of air in a room is calculated by multiplying its density by its volume.
Other Concepts
-
Metal Bolt's Density: A metal bolt with a mass of 34g is submerged in water increasing the water's level from 30cm³ to 42cm³. The density of the metal is 8.5g/cm³.
-
Equation to Calculate Liquid Density: The density of a liquid can be found using the formula: (mass of beaker + liquid)- (mass of beaker) / volume of liquid.
-
Gas Properties on Compression: The density and volume of a gas can change when compressed, but the mass and pressure do not change.
-
Weight Measurement and Mass: The reading on a newton meter, which is marked in N, correlates to the weight (force of gravity) and can be used to calculate an object's mass.
-
Effect of Heating on Air Molecules: When air is heated, the distance between air molecules increases and density decreases.
-
Mass of a Metal Disc: The mass of a metal disc remains unchanged when heated to 600 °C.
-
Mass and Weight at Different Locations: The mass of an object is constant independent of location; its weight is found by multiplying mass by the gravitational field strength.
-
Density of a Block: Using the formula density = mass/volume, the density of a regular-shaped block is calculated using mass and volume measurements.
-
Gravitational Field Strength: The gravitational field strength (g) effects an object’s weight, but not its mass.
-
Determining Mass from Weight: The weight of an object (measured in Newtons) is directly related to its mass (measured in kilograms) and the gravitational field strength. The weight is measured using a newton meter.
