Question

What is force and pressure?????

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.

Answer 2

$\underline\mathtt\red{FORCE:}$

Force is the external energy applied on a body to change its state of rest or motion.

$\underline\mathtt\red{PRESSURE:}$

Forces can be strong or weak, and can act over a large area or a small one. Pressure is a way of measuring how much force is acting over an area. A strong push on a small area creates high pressure, while a weak push spread out over a large area creates only a little pressure.
