Have you ever wondered what makes an object slow down or go faster? Well, join this class to find the answer to this interesting question.
The movement of an object depends upon the force and pressure applied to it. In this Mission Mid-Terms series, Saurabh Sir will take you through all the important concepts from your Class 8 Science chapter 11, Force and Pressure.
Some of the topics covered in this class are Force, Types of Force, Pressure, Pressure exerted
by Liquids, and Atmospheric Pressure in one shot. By the end of this class, you will be
able to solve any type of question-related to these topics. Saurabh Sir will lead you through all the concepts in a very interesting way.
A push or a pull on an object is called a force. Forces applied to an object in the same direction count to one another. “If the two forces act in the opposite directions on an object, the net force acting on it is the difference between the two forces.” Learn more about this in this class.

The video script covers the topic of force and pressure in a one-shot session for Class 8 Science. It explains the concepts of force, pressure, types of forces, and atmospheric pressure.

Key moments
00:00
The video focuses on force and pressure, highlighting their significance in everyday life. It also promotes an upcoming exam, offering scholarship chances and cash rewards for participants.
06:10
Force is the interaction between objects, leading to changes in speed, direction, or shape. Contact force, like muscular force, requires physical touch for application.
12:10
Contact forces require physical touch between objects, while non-contact forces like gravitational, electrostatic, and magnetic forces act without direct contact. Net force is the sum of all forces acting on an object.
18:12
Forces in the same direction add up, while opposite forces subtract. Balanced forces have a net force of zero, unbalanced forces have a non-zero net force.
24:17
Pressure is influenced by force and area, affecting objects differently. Nails, knives, heels, elephants, and bubbles demonstrate how pressure varies based on surface area and force applied.
30:19
Pressure by liquids and gases changes with depth, affecting bubble size. Atmospheric pressure is the weight of air column over Earth's surface.
36:39
Atmospheric pressure decreases as altitude increases, impacting activities like drinking through a straw and using suction cups.

Thank you very much sir, you helped me a lot and I got 49/50 marks in my exam❤🙂
Answer of the HW is option D
congrats
14:32 But sir aapke to baal hi nhi hai(MOYE MOYE)
What an explanation 😊!! Most of the people watching this video are students who have physics exam the next day
No, I just want to learn concepts

Don't talk in Hindi talk in English biology mam is very good but you
7:18 what are you speaking😂😂😂😂
😂
I got 10 out of 10 in test
D is the right answer
As pressure at most depth Is the most and decreases when depth decreases
Hey Kesar, Great🤩 Keep watching!

Force and Pressure
Thrust
❖ The force that acts on a surface in a direction perpendicular to it, is known as thrust.
Pressure
❖ Thrust per unit area is called pressure. So, pressure = force/area on which it acts.
❖ Liquids exert pressure on the walls of the container in which they are kept.
❖ Gases exert pressure in all directions.
Electrostatic Force
❖ A force exerted by a charged body on another charged or uncharged body is known as electrostatic force.
❖ Atmospheric pressure is defined as the pressure exerted on a surface by the weight of air above that surface.
Atmospheric Pressure
❖ The pressure exerted by atmospheric air around us is known as atmospheric pressure.
Contact Force
❖ A force that can be applied only when it is in contact with an object is called a contact force. For example,
hammering a nail.
Electrostatic Force
❖ When a charged body, either having a (+) or (-) charge, exerts force on another charged or uncharged body, that
force is known as electrostatic force.
Force
❖ Simply a push or pull exerted by an object on another is a force.
Friction
❖ The force of friction always acts on all the moving objects and its direction is always opposite to the direction of
motion.
Gravitational Force
❖ The force exerted by the earth to pull the objects towards itself is called the force of gravity.
Gravity
❖ Every object in the universe, whether small or large, exerts a force on every other object. This force is called the
force of gravity or just gravity.
Magnetic Force
❖ The force exerted by a magnet to pull/push a metallic object is called magnetic force.
Muscular Force
❖ The force resulting due to the action of muscles is known as muscular force. For example, writing, cutting
vegetables.
Non-Contact Forces
❖ A force that can be applied without any contact between two objects is called non-contact force. For example,
the magnet pulls the iron-pieces.
Pressure
❖ The force acting on per unit area, applied to an object in the direction perpendicular to the surface is called
pressure.

What r the causes of force?
When any object intereact with another object.hence, force is caused.
14:29 sir but aap ke to baal hi nhi Hai 😢😅
The answer for home question is D
Thanks sir for this one shot series
Best teaching compared to all teacher
I had buy physic wallah course but he was worth of money

I am studying this chapter
Loved the explanation
23:00 pressure start
The answer Is d pa
Pic institution is better than byJus
But sir How Do we know that material we are creating will be able to withstand the pressure of 4 to whatever number of elephants
answer is Pa
Sir u r nextlevel op❤❤
Your teaching style is very differnt and so enjoyBle
Thanks sir for teaching this chapter ❤
@ tutor,
Sometimes you are talking in english and sometimes you are talking in hindi... If a child doesn't know hindi, how can he/she understand the chapter clearly. PLEASE talk in english.
And what if o kid don't know english..??
Homework question ❓
Ans D for sure 🎉
Thank you byjus for these type of videos. When I’m absent I’m unable to understand the topics taught after that so I take help from these videos. Sir the bestest
A ball is coming to u and u say hatt and it changes direction, wthh 😭😭😭😭😭😭 that was so good 😭😭😭😭
Wow , what a class I really enjoyed it
Hey Likitha, Glad you enjoyed the session🤩 keep watching!!
Form 13:50 what sir say's 😂😂😂
sir, I have a doubt if we suck out or manage to take all air particles of a small paper box like matchstick box, inflates, if we do the same thing with a big room whose walls are made up of bricks, then what will happen, will it inflate of the shape remains the same?
because the force the pressure is still applying on it from outside but not rom inside, and if it is so simple to destroy houses or buildings to use that land to build more of them, why don't we use this way instead of all jcb's and heavy heavy machines?
lol dumbo
jjk😊
@@luckeykumar-7798 jujutsu kaisen?
yess
No it won't inflate because a room made up of bricks have tiny pore from which air can pass 😅 (its my theory i cant give the currect ans because i am also a student)
It was really good explanation. Thank you sir. I always can't understand the force and friction . When I see this vedio all my doubts was clearly. You are amazing sir 😍
Before exam is OK but seeing video on the day u have exam is next level

Bro you are in central academy ?

23:15 goes like balabalababaabalallababbab🤣🤣🤣
Answer- C (homework)
No answer is (a) because b and c are at same depth and therefore exerts same pressure. While a is very up and therefore exerts a little pressure therefore pa
7:58 😂😂
I have challagne for all students wathing this veideo
Solve this question.
abc(a+b+c)×abc+abc=x?????????
Yah thats very difficult
If you solve this problem you are the best maths student.
There is no value given in the R.H.S if there is a value only we can solve it
You didn't give any algebraic function also
The value of all a,b,c and x is 0🤣😂😀
Sir aap ko sound increase karna padeee gaa 😂😂
Sir really thank you it helped me a lot im good in physics but my expressing part is a little bad and you gave that with a real ease thank you
Weeeeeeèeeeeeeeeeee weeeeeèeeeeeee
Thanks sir for teaching us free of cost 😀
sir is back bencher in school 😂😂
Very good explanation sir... The concept was easy to learn
Hey Smitha, Thank you so so much😍 Keep learning!
