- The image depicts a sphere submerged in a fluid, with arrows indicating forces acting on it from all directions.
- The upward arrow represents the buoyant force, which is the net upward force exerted by the fluid on the submerged object.
- The downward arrow represents the weight (gravitational force) of the object.
- The horizontal arrows represent pressure forces from the fluid acting on the sides of the object; these cancel each other out because pressure at the same depth is equal in all directions.
- For an object to be in equilibrium while submerged, the buoyant force must equal the object’s weight.
- If the buoyant force is greater than the weight, the object will rise; if less, it will sink.
Parent Tip: Review the logic above to help your child master the concept of density and buoyancy worksheet.
