Why do some objects sink while others float in water?

Explanation:

Objects that float or sink in water depend on their density and the buoyant force. When an object is placed in water, two forces act on it: the force of gravity pulling it downward, and the buoyant force pushing it upward. If the weight of the object is greater than the buoyant force, the object will sink. If the weight is less than the buoyant force, the object will float.

Factors determining whether an object sinks or floats:

• Density: Objects with a higher density than water will sink, while objects with lower density will float.
• Shape and size: Objects with a larger surface area relative to their weight are more likely to float due to increased buoyant force.
• Material: Materials like wood, rubber, plastic, egg, palm leaves, styrofoam, and some types of natural rocks have lower density and are more likely to float in water.

Understanding these principles helps explain why some objects sink while others float in water.
