Why Do Some Heavy Objects Float and Other Heavy Objects Sink?
Whether an object sinks or floats in a fluid (liquid or gas), depends on several variables:
Does the Bowling Ball In The Diagram Sink or Float?
The diagram shows the bowling ball on the bottom of the container of water. But, assuming it is being held in place on the bottom, will it float when released?
1. If the density of the bowling ball is greater than the density of the water it is submersed in, it will not float. If the ball’s density is equal to or less than the density of the water, the ball will float.
d = 5.5 kg ÷ 4.5 liters
= 1.2 kg/1liter or 1.2 kg per 1 liter
d = 4.5 kg ÷ 4.5 liters
= 1.0 kg/1liter or 1.0 kg per 1 liter
