A log will float in water because a log is less dense than water. If you take any number of objects/substances that don't mix immidiately (ex: water, molasses, oil, ice, a cork and/or a rock) and put them in a container together the items will settle into layers by density (salad dressing does this too). The bottom layer will be the most dense and the top will be the least. You can actually do this experiment yourself with a clear drinking glass as the container. Interesting factiod: Not all wood floats in water. There are a few types of wood (Ebony, Lignum Vitae) that are denser than water and therefore do not float.
because its gravity and it allows the log to float
An object will float on water if it has less density than the water. Or than any other liquid on which it is supposed to float.
It is lighter than water.
Yes, the density of wood (Oak) is less than water.
A log? As in a log that came from a tree, right? If the density of water was decreased enough, such that it is now lower than a log's density, then the log would no longer float, but sink.
Actually, the steel needle can float on water as well, so long as the surface tension is not broken. Answering the question, the buoyancy (ratio of density to that of displaced water) causes the log to float.
The water extracted by the wood log while floating is of equal weight of the wood or more. For this reason, the log of wood floats while a steel needle sinks.
Doesn't always, depends on amount of air inside, if it is less dense than water, it will float.
People do not sink in Saline water as the salt makes the water heavy and like a log of wood people float in water.

Because of the density
A boat can float on the water, and a submarine can float in the water.
Jeremejevite does not float on water.
What sediment float in the water
They float in water.
no gravel does not float on water.
Water does not float on more water. Water combines into ... water.
Yes porcupines do float, all porcupines float in water
Rocks that float on water: pumice. Rocks that do not float on water: all other rocks.
yes iron does float in water yes iron does float in water
in order for granite to float on water, it has to be lighter than water. because if its heavier than water, it will not float!
Well not all organs can float, but lungs can float on water
There are tents designed to Float in water. But not all tents designed to float.
Yes, bananas do float in water.
