Data analysis:
1. Plot the graph of W against F .
D B
2. Calculate the gradient of the graph.
Conclusion:
What conclusion can be drawn from this experiment?
Prepare a complete report for this experiment.

Discussion:
1. What is the value of the gradient of the graph?
2. State the relationship between the buoyant force and the weight of water displaced based on
the results of the experiment.

Figure 2.30 shows the flow and relationship between the concepts involved in Experiment 2.3.

Object
Object Object experiences Buoyant force
Object in the air submerged in displaces apparent loss acts on object
liquid liquid in weight

Weight of object Weight of Volume of liquid Apparent loss in Buoyant force
in air is the object in liquid displaced = weight of an object = = weight of
actual weight is the apparent volume of the weight of an object liquid displaced
of object weight of object submerged part in the air – weight of
of the object an object in liquid

Figure 2.30 Relationship between concepts that explain buoyant force and the weight of liquid displaced

Buoyant force = Weight of liquid displaced
= Apparent loss in weight
