Enter the total buoyancy (N) and the opposing forces (N) into the Calculator. The calculator will evaluate the Net Buoyancy.

## Net Buoyancy Formula

NB = TB - OF

Variables:

- NB is the Net Buoyancy (N)
- TB is the total buoyancy (N)
- OF is the opposing forces (N)

To calculate Net Buoyancy, subtract the opposing forces from the total buoyancy.

## How to Calculate Net Buoyancy?

The following steps outline how to calculate the Net Buoyancy.

- First, determine the total buoyancy (N).
- Next, determine the opposing forces (N).
- Next, gather the formula from above = NB = TB – OF.
- Finally, calculate the Net Buoyancy.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

total buoyancy (N) = 1400

opposing forces (N) = 200

## FAQ

**What is buoyancy?**

Buoyancy is the force exerted by a fluid that opposes an object’s weight. In simpler terms, it’s what allows objects to float or sink in water or any other fluid.

**How does the density of an object affect its buoyancy?**

The density of an object compared to the fluid it’s in determines whether it will float or sink. Objects with a density lower than the fluid will float, while those with a higher density will sink.

**What are some practical applications of understanding buoyancy?**

Understanding buoyancy is crucial in various fields such as marine engineering, designing swimming pools, submarines, and ships, as well as in search and rescue operations to calculate the buoyancy needed to lift objects from underwater.

**Can the net buoyancy ever be negative?**

Yes, the net buoyancy can be negative if the opposing forces (like weight or downward pressure) are greater than the total buoyancy force. This scenario typically results in the object sinking.
