**Archimede's Principle ** ==Buoyancy is what makes an object float in liquids. According to Archimede's Principle objects feel lighter when submerged under water. When an object is underwater it is buoyed upward with the same ammount of force as the displaced fluid causing it to float.==

**Gravity ** ﻿  **Gravity pushes the object in the water downward while the buoyant force pushes upward causing the object to stay afloat**.
 * When the the object is submerged it expands the depth of the fluid creating space for the object to float. **

Without buoyancy nothing would stay above the water.(Jones 83)

 * Objects that float are positivly buoyant. Objects that don't float are negitivly buoyant. An object will float if the buoyancy is greater than the weight of the object. **
 * The buoyant force is equal to the weight of the displaced fluid, The force will increase if more fluid is displaced (Jones 84). **
 * Objects can also have buoyancy in the air. Such as balloons. **
 * When objects are in different liquids their buoyancy differs. In salt water the object would float more above water, while in oil it would submerge underneath more. **
 * An object will float or sink depending on the density. **
