The meaning of FLUID is having particles that easily move and change their relative position without a separation of the mass and that easily yield to pressure : capable of flowing.

fluid adjective (LIKELY TO CHANGE) If situations, ideas, or plans are fluid, they are not fixed and are likely to change, often repeatedly and unexpectedly:

FLUID definition: a substance, as a liquid or gas, that is capable of flowing and that changes its shape at a steady rate when acted upon by a force tending to change its shape. See examples of fluid used in …

Fluids flow easily and take on the shape of their containers. All liquids and gases are fluids.

A liquid is a fluid — something that flows easily when poured — although gases can also be called fluid. When your doctor told you to drink lots of fluids to help your cold symptoms, she probably meant …

A situation that is fluid is unstable and is likely to change often. The situation is extremely fluid and it can be changing from day to day.

In physics, a fluid is a liquid, gas, or other material that may continuously move and deform (flow) under an applied shear stress, or external force. [1] They have zero shear modulus, or, in simpler terms, …

Section Summary A fluid is a state of matter that yields to sideways or shearing forces. Liquids and gases are both fluids. Fluid statics is the physics of stationary fluids.

In contrast, liquids deform easily when stressed and do not spring back to their original shape once the force is removed because the atoms are free to slide about and change neighbors—that is, they flow …
