## Question:

How does Archimedes' principal work in a vacuum such as space?

## Archimedes' Principle:

Archimedes principle states that the weight of water displaced when submerging an object is equal to the upward, buoyant force exerted on the object. The buoyant force is not necessarily equal to the weight of the object, but it must be equal or greater in order to make the object float and counteract the downward force of gravity.

In a vacuum such as space, objects experience no gravitational force. Therefore, placing an object on a body of water would have no effect. It would not sink into the water, nor would the water stay in the container. Thus, there would be nothing sinking in the water, and thus no buoyant force pushing it back up. If you could somehow corral the water into the container and then pushed the object down into the water, there would be a buoyant force acting up on the object equal to the water displaced.
