float
You can put a uniform object into water.If it sinks density is higher than water,if floats lesser than water.If you can place anywhere in water,density is equal to water.
An object will sink if it weighs more than the water it pushes away, and an object will float if it weighs less than the water it pushes away. The Greek mathematician Archimedes discovered that the amount of water displaced by an object depends on the mass of that object. Mass is the amount of matter in a substance, and dense objects have more mass than less dense objects. Dense objects that do not displace much water will sink, while less dense objects that displace a lot of water will float.
When an object is placed in a less dense liquid or gas, it will experience a buoyant force acting against gravity. If the object's density is greater than that of the surrounding medium, it will sink; if the object's density is less, it will float. The object will displace a volume of the medium equal to its own volume.
An object will float when it has less density than the fluid or substance that it is placed in. The object floats upward due to buoyant forces. Similarly, objects will sink if they are dense than the fluid.
An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
An object will float if it is less dense than the liquid it is placed in. An object will sink if it is more dense than the liquid it is placed in.
Density can cause things to move when a less dense object is placed in a more dense fluid, such as water. The less dense object will float because it displaces an equal weight of the more dense fluid. This creates an upward buoyant force that pushes the object to the surface.
A wooden block can be less dense than water.
ok so when the object hits the water, the water pushes up with the same amount of force (boyancy ) but if the object has a greater density than the water then the object has more force pushing down on the water and then it sinks. more dense=sink, less dense =float
