Motion in a plane, also known as two-dimensional motion, refers to the movement of an object in a flat, two-dimensional space. This type of motion involves two coordinates, typically x and y, which describe the object's position in the plane. Here are the key aspects of motion in a plane:
1. Position and Displacement:
Position is specified by a vector r with components (x, y).
Displacement is the change in position, represented by Δr = r2 - r1.
2. Velocity:
Average velocity is the displacement divided by the time interval, v avg = Δr/Δt.
Instantaneous velocity is the limit of the average velocity as the time interval approaches zero, v = dr/dt.
3. Acceleration:
Average acceleration is the change in velocity divided by the time interval, a avg = Δv/Δt.
Instantaneous acceleration is the limit of the average acceleration as the time interval approaches zero, a = dv/dt.
4. Equations of Motion:
These equations describe the relationship between displacement, velocity, acceleration, and time.
5. Projectile Motion:
A common example of motion in a plane is projectile motion, where an object moves under the influence of gravity. The horizontal motion has constant velocity, and the vertical motion has constant acceleration due to gravity.
6. Uniform Circular Motion:
When an object moves in a circle at a constant speed, it experiences centripetal acceleration directed towards the center of the circle.
By analyzing these components, physicists can describe and predict the behavior of objects moving in two-dimensional space.

Sir l literally waiting for this chapter ❤
And I sure that ur channel will soon get 3 million subscribers. 🎉
Sir, Very Very Very much thanks it is Very Much crystal clear now. Thanks. Thanks ❤❤❤❤❤❤❤❤
Sir literally waiting for your class ., it’s very beneficial to students like me who have zero knowledge in physics your videos are very helpful thanks sir
I Have love it the way of your teaching.Please do on chemistry?❤
Sir, Your youtube channel and your explaining videos are truck of knowledge for us And also very useful channel for maths and physics students . I learnt so many from you such as maths and physics.
Q. An object is thrown straight up. Time taken by it to reached the maximum height
is 4sec. Calculate the distance after 2sec when it was thrown?
sir, i am in confusion
according to my calculations the position vector of the final velocity is 3i + 6j .
you wrote 3i + 12j.
how 2 magically appeared at the time of multiplication by t=3?
Differentiating t square will get 2t
i still don't get it can anyone explain please?
@@spoorthiav8111 its just differentiation brother like if we differentiate t^2 then we will get 2t (ie , we multiply the power with t and reduce the power by one , for example differentiating t^3 u will get 3t^2 ). Guess i have solved the doubt
Average acceleration and acceleration are different entities. Please, correct it, sir. And for delta it better use 'd' for difference ( differential calculus) . Don't confuse us.
Sir need more video like this as soon as possible can you pls start 12 physics also🙏🙏🙏🙏🙏🙏
Sir please come up with dedicated jee series for both class 11 and 12🙏🙏... Live u sir 🙏❤️
What is the energy convertion when a car is moving uphill. Is chemical energy to mechanical energy correct?
acceleration is 4m/s^2??
Sir how can you cite an example of a car for 2d motion...for learners its quite confusing
I have learnt a lot from ur classes sir tq vry much
Sir, can you make a video for the justice of Bangladeshi students.
Keep it up!!
Thanks!
❤❤ very nice sir
Thanku so much Sir
❤👍🏻
Sir can you please tell me about what is elements
Good explanation
acceleration = +4j
a(t)=3i/t + 3j
sir nice video but sir why are you not live for past three years i watch your video from 7th and today i'm in 9th and still watching your video
Tq sir i want this video
Sir please will you upload chemistry 11th standard stucture of atom 2nd lesson plz sir 🙏
Bhaiya plz physics numericals
Waiting for you...... And you surprised us ❤
Ha ha ... thanks!
Sir I just madly fell in love with you, please may I know your name
nice
Thanks!
Displacement itself a vector, then why did you say displacement vector, Velocity vector,.. etc., everytime? Is it meaningful in saying this?
Let's say a body moves from A to B. Displacement vector is the vector drawn from point A to point B.
@@ManochaAcademy you can say "Displacement" and not " displacement vector".
U r foolish, Sir was correct
@@SivaKumar-mu5pjbruh so what why the f do you even need to be Soo specific the point is you understood it or not
@@SivaKumar-mu5pj
If u knew everything then just don't come again💩
Sir your alll viodioes are very helpfull sir ..tq so much sir🎉🎉🙏🙏
Most welcome!
🎉🎉🎉❤❤❤
Thanks!
I was eagerly waiting for this video, thank you so much sir
First view first comment sir❤
Thanks for watching so fast!
Damn
Is there anything he expalined without practicals
I wish you all the best sir
Just like PW you will also get ur institute expanding like fire
Great to hear that you like our videos! Thanks!
Sir I want one suggestion.😢 Physics is very difficult to me 😢 how to learn sir
Focus on understanding the concept first. Take your time to do that and then practice questions. All the best!
Hehehheeh! Video like krke save krli hai😂I will watch it one day before exam
Ha ha ... don't watch it 1 day before :) Watch now!
Sir please mention your name before start the class in next class
Hi sir
Hi, thanks for watching!
a(t)=3i/t + 3j
hi sir
Hi, thanks for watching!
