The motion of liquids (usually
water
) around a solid object. The Kinetic Molecular Theory states: -all matter is composed of molecules or other types of particles. The buoyant force on an object immersed in fluid is equal to the weight of the fluid that the object displaces (EUREKA!!)
What are fluids answer?
Fluids are
substances that can flow
. They include liquids and gases. Since these substances can flow from one place to another they are called fluids. They don’t have any fixed shape.
What are fluids in science grade 8?

What are fluids explain?
A fluid is
any substance that flows or deforms under applied shear stress
. Fluids comprise a subset of the states of matter and include liquids, gases, and plasma.
What is meant by fluid mechanics Grade 8?
fluid mechanics. the
study of how fluids behave while still and in motion
.
What are the properties of fluids Grade 8?
| Force A push or pull that causes changes in movement. | Streamlined Shapes that create laminar flow | Viscosity The resistance of a fluid to flowing and moving ( ketchup is more viscous then water) | Cohesion The attractive forces among particles ( the relationship between ketchup and the bottle) |

What are 3 fluids that are essential to life?
- Blood. Blood plays a major role in the body’s defense against infection by carrying waste away from our cells and flushing them out of the body in urine, feces, and sweat. …
- Saliva. …
- Semen. …
- Vaginal fluids. …
- Mucus. …
- Urine.
What are fluids give 2 examples?
Two examples – Fluids are substances that have the ability to flow.
Gases (oxygen, hydrogen)
, for example, and liquids (water, petrol, sulphuric acid).
What are examples of fluids?
- Water.
- Air.
- Blood.
- Honey.
- Milk.
- Oil.
- Shampoo.

What are the types of fluids?
- Ideal Fluid. An ideal fluid is incompressible and it is an imaginary fluid that doesn’t exist in reality. …
- Ideal plastic Fluid. …
- Real Fluid. …
- Newtonian Fluid. …
- Non-Newtonian Fluid. …
- Incompressible Fluid. …
- Compressible Fluid.
How are fluids used?
Fluids have many uses, including
holding and transporting other materials
. Substances in their fluid form can be shaped and then cooled to become solids. Whether it is a race car or a family car, an automobile needs fluids and fluid technologies to run smoothly, safely, and efficiently (Figure 7.3).
Are all fluids liquids?
All liquids are fluids
but not all fluids are liquids. Fluids are described as something that can flow as a result of a pressure differential between two points. Liquids, on the other hand, are a subset of liquids. Liquids are incompressible liquids.
What is a fluid simple definition?
Fluid,
any liquid or gas or generally any material that cannot sustain
a tangential, or shearing, force when at rest and that undergoes a continuous change in shape when subjected to such a stress.
What are 2 characteristics of all fluids?
In conclusion, two fluid characteristics are
“Viscosity” and the “Absence of shape memory”
.
How do I calculate flow rate?
Flow rate is the volume of fluid per unit time flowing past a point through the area A. Here the shaded cylinder of fluid flows past point P in a uniform pipe in time t. The volume of the cylinder is Ad and the average velocity is ̄ ̄ ̄v=d/t v ̄ = d / t so that the flow rate is
Q=Ad/t=A ̄ ̄ ̄v Q = Ad / t = A v ̄
.
What is the flow rate Grade 8?
Flow rate is how fast a fluid moves from one point to another. Measuring flow rate of gases can be a little difficult, for now we will focus on liquids.
