Question

Define both pressure and Force ?????

in very detail

no need to copy

Answer 1

FORCE :-——

⭐Force can be defined as any push or a pull that changes/tends to change

➡ the state of rest or of uniform motion of an object or

➡ changes the direction or

➡ shape of an object.

⭐It causes objects to accelerate.

⭐In SI base units:- kg·m/s2

⭐Unit S.I = Newton

⭐Force intuitively described as a push or a pull.

⭐ A force has both magnitude and direction.


⭐ it a vector quantity.

⭐It changes speed of moving object or directions or can deform its shape of can change the direction of object.

PRESSURE:———

⭐Pressure is the force applied perpendicular to the surface of an object.

⭐Pressure is an expression of force exerted on a surface per unit area.

⭐Pressure means how much something is pushing on something else.

⭐It is expressed as force per unit area:

⭐ Pressure=Force/Area.

⭐Types of Pressures :—

✨Absolute
✨Atmospheric
✨Differential
✨Gauge Pressure.

⭐Examples : pressure in breathing, hammering.

⭐The bar is a unit of pressure defined as 100 kilopascals.
