Question

A piece of wood floats on water (true or false).

Answer 1

Hint: To address this topic, we must first comprehend density and its variations. Anything with a lower density will float on top of liquids. The density of a substance refers to how heavy it is in relation to its size. A substance's density is one of its distinguishing characteristics.

Complete answer:
The answer to this question is true. Wood floats on water because it is less dense than water, regardless of how large or little the piece of wood is. If you compared the weight of wood to an identical amount (or volume) of water, you'd find that the wood sample weighs less. This indicates that wood has a lower density than water. The buoyant force on wood will be equal to the weight of the wood piece.
We can also say that an upthrust force also acts on an object. If the density of the object is less than upthrust is more and vice versa.Up thrust is also known as buoyancy. We can also explain this answer in terms of buoyancy force acting upon the object. If the buoyancy force is positive the object floats and if the buoyancy force is negative the object sinks.

Note:
We are purposely using the terms “size” and “amount” instead of “volume” in discussions of density. We are also using “heavy”, “light”, and “weight” instead of “mass” difference between mass and density The key difference between density and weight is that weight is a measure of the amount of matter in an object, whereas density measures the amount of matter in a unit volume.
