There are three different types of buoyancy:
1. Positive buoyancy: This occurs when an object is less dense than the fluid it is placed in, causing it to float. Real-life examples of positive buoyancy include balloons filled with helium, ice cubes in water, and boats floating on the surface of the water.
2. Negative buoyancy: This occurs when an object is more dense than the fluid it is placed in, causing it to sink. Real-life examples of negative buoyancy include rocks dropped into water, submarines submerging underwater, and metal objects sinking to the bottom of a pool.
3. Neutral buoyancy: This occurs when an object has the same density as the fluid it is placed in, causing it to remain suspended at a constant depth. Real-life examples of neutral buoyancy include fish swimming at a specific depth in water, divers using special equipment to stay in place underwater, and helium balloons held at a certain height in the air.
