Fluid Definition
Fluid Definition
Any substance that can continuously change its shape under applied force.
Shear Modulus of Fluids
Shear Modulus of Fluids
The shear modulus of a fluid is zero, meaning it cannot resist any force that tends to deform its shape.

Study Notes
Definition and Properties of Fluids
- A fluid is a substance that flows and has no fixed shape, taking the shape of its container.
Mechanical Behavior of Fluids
- Fluids do not have a shear modulus, as they do not resist shear stress.
- In rheology, substances can exhibit both fluid and solid properties, depending on the stress applied.
Non-Newtonian Fluids
- Non-Newtonian fluids, like Silly Putty, exhibit non-linear behavior when a sudden force is applied, where their viscosity changes in response to the force.
Extended Concept of Fluid in Particle Physics
- In particle physics, the concept of a fluid is extended to describe the behavior of particles in high-energy collisions, where particles can exhibit fluid-like behavior.
