What word describes objects that float?
Buoyant.
What 2 things exert buoyant force?
Two things that exert buoyant force are fluids (such as water or air) and objects submerged in those fluids. Buoyant force is the upward force exerted by a fluid on any object placed in it, which helps objects to float.
Do objects of different densities and same volume have the same buoyant force?
No, objects with different densities and the same volume will displace different amounts of fluid when submerged, resulting in different buoyant forces acting on them. Buoyant force depends on the weight of the fluid displaced, so objects with different densities will experience different buoyant forces.
What is the force that is working against the buoyant force?
The force working against the buoyant force is gravity. Gravity pulls objects downward, while the buoyant force pushes objects upward when they are immersed in a fluid.
Why are some objects more buoyant then others?
Objects with a lower density than the fluid they are in will be more buoyant. This is because the buoyant force that an object experiences is equal to the weight of the fluid displaced by the object, so if the object is less dense, it will displace more fluid and experience a greater buoyant force.
