Atmospheric pressure refers to the force exerted by the weight of the atmosphere on a unit area of surface. Essentially, it's the weight of the air above a given point on the Earth's surface. As you move closer to the Earth's surface, the weight of the air above you increases, hence increasing atmospheric pressure. Conversely, as you move higher in altitude, atmospheric pressure decreases since there's less air above you. This pressure is crucial for maintaining Earth's climate and supporting life as we know it.
The atmospheric pressure at sea level is approximately 100,000 pascals. Atmospheric pressure value is 101.325 kilopascals (kPa). However, atmospheric pressure can vary depending on factors such as weather patterns, altitude, and geographical location. For instance, high-pressure systems typically bring higher atmospheric pressure, while low-pressure systems bring lower pressure. Additionally, atmospheric pressure decreases with increasing altitude; at higher elevations, such as on top of a mountain, atmospheric pressure is lower than at sea level.

Sir please make videos about 10 th physics cbse syllabus

@sukhbhandal6299 Ай бұрын

Your videos are so helpful I score 100% every single time god bless you I went from failure to success students in under 1 month from your videos the are so short and to the point Plz give me shout out in the next video it will mean a lot

the blood pressure inside our body cancels the effect of the atmospheric pressure. Thus we don't feel the atmospheric pressure.

I have improved in my studies because of you thanks

The blood pressure in our bodies is equal to the atmospheric pressure out side our bodies hence creating a net force of 0N 4:37

Fantastic Explanation sir!! 😁

@himanihaldar6835 Ай бұрын

We do not feel atmospheric pressure as our bodies are used to it and the pressure inside our body is same as the pressure outside our body therefore, we do not get crushed and out body is flexible to adapt with changes in air pressure .

Sir I want to study about stars and galaxies in physics

It's because the internal body pressure is equal to the atmospheric pressure

@sumansinhababu270 Ай бұрын

why pressure is scalar quantity

@maheshshorts556 Ай бұрын

Because The pressure of our body and pressure of atomsphere is equal and they cancel ecah other.

@bandinageswararaobandi7741 Ай бұрын

Air pressure is applied on all sides equally, so we never feel pressure

@tamannasantamoni8229 Ай бұрын

Actually as the blood pressure inside our body is slightly higher than the atmospheric pressure, we, that is why, do not feel the atmospheric pressure.

The blood pressure gets cancelled with atmospheric pressure. Thats why if we go to hills blood pressure is higher than atmospheric pressure and blood comes out of our body.

@SrijitaSahaOfficial Ай бұрын

Because our internal blood pressure balances the outer pressure thus we do not feel anything -Srijita Saha, class 8 ICSE Science combo subscriber student

Are you from India

@harsharunprasadh5779 Ай бұрын

we don't feel atmospheric pressure because the blood pressure is almost equal to the atmospheric pressure so it neutralizes the pressure so we can not feel it

You have great knowledge

Force=0 if acceleration is not =0 or if Acceleration =0 , force is not =0 is this possible

@SuorkuthkShutgdjn 6 күн бұрын

This is not possible Because a body accelerate due to an unbalance force. Since Unbalance force = 0 Thus , Force = 0 and acceleration is not 0 not possible.

@@SuorkuthkShutgdjn Sir thanks for your better explanation but when i ask from some physics teacher about it some one said me its possible someone say not possible
