The weight of a body as affected by the buoyancy of a fluid (such as air) which it is immersed, being the true weight minus the weight of the displaced fluid, is called apparent weight.

Within elastic limit, stress is directly proportional to strain. Mathematically we may write, stress ∞ strain.

When a body falls freely under the gravitational force and except this force, no other force works on the body, then it feels that it has completely lost its weight. This phenomenon is called weightlessness.

Biomass is the amount of living matter (as in a unit area or volume of habitat) or it is a source of energy that is obtained from plant materials and animal waste.

The ability of a fluid to exert an upward force on an object that is immersed in it called buoyancy. The upward force that liquid or gaseous matter applies perpendicularly on an object partially or completely submerged in the liquid or gaseous matter is called buoyancy. or, Buoyancy is an upward force exerted by a … Read more

The phenomenon of the transformation of a liquid from its liquid state to a gaseous state is called vaporization.

For the scientific purposes, any number is expressed as a product of a number from 1 to 10 and power of ten. This type of expression of numbers is known to be scientific symbols.

If an object has one-meter displacement towards force from applying one-newton force on it then the amount of work done is called one joule.
