Study Notes
Floating and Sinking
- The density of an object determines whether it floats or sinks.
- Density is the amount of matter packed into a given space.
Buoyancy
- Buoyancy is the upward force exerted by a fluid that opposes the weight of an object.
- If the buoyant force is greater than or equal to the weight of the object, the object floats.
- If the buoyant force is less than the weight of the object, the object sinks.
Displacement
- Displacement refers to the amount of fluid that is pushed aside by an object.
- The volume of fluid displaced is equal to the volume of the object.
- The greater the volume of fluid displaced, the greater the buoyant force.
Factors Affecting Floating
- The density of the object determines its buoyancy.
- A ship's hull is designed to displace a large volume of water, increasing the buoyant force.
- The shape and size of an object impact its buoyancy.
- The weight and density of the water determine its buoyancy.
