Question

What is a fluid? What is fluid pressure?​

Answer 1

$❤ANSWER❤$

Fluid pressure is a measurement of the force per unit area on a object in the fluid or on the surface of a closed container.

This pressure can be caused by gravity, acceleration, or by forces outside a closed container.

Since a fluid has no definite shape, its pressure applies in all directions.

hope it will help you ✌

Answer 2

Answer:

In physics, a fluid is a substance that continually deforms under an applied shear stress, or external force. Fluids are a phase of matter and include liquids, gases and plasmas. They are substances with zero shear modulus, or, in simpler terms, substances which cannot resist any shear force applied to them.

Fluid pressure is a measurement of the force per unit area on a object in the fluid or on the surface of a closed container. This pressure can be caused by gravity, acceleration, or by forces outside a closed container. Since a fluid has no definite shape, its pressure applies in all directions.
