Types of Forces
Buoyancy is the force that pushes upward on an object placed in a fluid (gas or liquid).
An object placed in a fluid (gas or liquid):
How to Measure the Buoyancy Force on an Object placed in Water.
1. Weigh the objects to be placed in the water.
2. Fill the large container with water so that the water’s surface is just below the straw as shown.
3. Place the object in the water and allow the displaced water to drain into the collecting container.
4. Weigh the collecting container and displaced water. Subtract the weight of the container and the answer is equal to the water’s buoyancy force pushing up on the object.
