There is a concept called Active Gravitational force and passive gravitational force. Active gravitational force accounts for the gravitational field strength of a massive object, whereas passive gravitational force accounts for how other objects gravitate in the gravitational field of the former one. The concept of acceleration due to gravity comes in the category of passive gravitational force. F= Ma or a= F/M . An interesting thing here is that in an active gravitational field the force acting on any mass is proportional to its mass and every time the ratio between force to mass taken, the result arrives is a constant, which is the acceleration due to gravity. Another important thing is that, when two bodies are gravitationally interacting, one with extreme larger mass (M) like earth and other with smaller mass(m) stone , the force between them is equal and opposite but due mass difference the stone will accelerate towards earth with constant acceleration of appreciable magnitude(roughly 9.8 ms^-2) whereas the acceleration of earth although constant towards the stone is so negligence to be detected. But between the sun (with extremely larger mass compared to earth) and earth the centripetal acceleration of earth towards the sun is of great magnitude. Simple formula: F= M A =ma, if F is constant then for M>>m, A

Apple Force ( formerly known gravitational force ) draws any object to its center ( and here, the surface of the earth is not center but the resting place with specific Apple Force power consumption ) at the same acceleration rate of 9.8 meter per second but gets squired when a falling mass holds up the Apple Force motion incrementally in same manner, reaching towards the distance to its center until gets obstructed or being at rest, to which the earth planet is being compacted. Either the earth or any object falling towards it doesn't attract each other rather they are compacted with specific Apple Force power.
My name is jatin Kumar from faridabad haryana . I am preparing for neet 2025. Wave theory says that When a black body is heated then the intensity of flame increase not the color change. Particle theory says that intensity has no impact of temperature, it says that the freq increases and leads to the change in color. And in the ncert of class 11 chem . It is written - when an iron rod is heated in furnace it is initially dull red but as temp inc. it becomes bright or dark red . ( Wave theory) But in the next line it is written that the color change from red to blue. So my doubt is that here both theory are used and could not justify that intensity inc. or color change

See potential means degree of unstability means if I have a spring which is fixed at one end and I have not done anything to that spring then it is in its normal or stable state or 0 potential but when I stretch it I disturbed from its normal state , at that point it has some degree of unstability and that is called as potential.

Helicopter Location on Earth. User If a helicopter is flew for 20 hours on stationery location at a fixed place in India, after 20 hours will it change the place as Earth rotates ? ChatGPT Yes, if a helicopter remains stationary at a fixed location on the surface of the Earth for 20 hours, it will change its location due to the rotation of the Earth. The Earth completes one rotation on its axis in approximately 24 hours. Therefore, during the 20 hours the helicopter remains stationary, the Earth rotates by approximately 20/24 or 0.833 degrees. This means that the location of the helicopter on the Earth's surface will have changed by 0.833 degrees due to the Earth's rotation. The exact distance the helicopter has moved depends on its location and the distance from the equator. The distance covered by the helicopter can be calculated using the formula: distance = (angle in degrees) x (pi/180) x (radius of the Earth) Assuming the helicopter is at the equator, which has a radius of approximately 6,371 kilometers, and the change in position due to the Earth's rotation is 0.833 degrees, the distance covered by the helicopter in 20 hours would be approximately: distance = (0.833) x (pi/180) x (6,371) = 147.8 kilometers Therefore, after 20 hours, the helicopter would have moved approximately 147.8 kilometers due to the Earth's rotation. User If a helicopter is flew for 20 hours on stationery location at a fixed place in India, after 20 hours will it change the place as Earth rotates? Which country will it be ? ChatGPT If a helicopter remains stationary at a fixed location in India for 20 hours, it will change its location due to the rotation of the Earth, as explained in my previous answer. However, the helicopter will still be in India after 20 hours, just in a slightly different location. The change in the helicopter's position due to the Earth's rotation is determined by the latitude and longitude of its initial position. Assuming the helicopter is initially located at a fixed point on the ground in India, its new position after 20 hours will still be in India, just shifted slightly due to the Earth's rotation. The exact location within India where the helicopter will end up after 20 hours depends on its initial position, as well as the latitude and longitude of that position. The change in position due to the Earth's rotation will be different for different locations within India. However, it is safe to say that the helicopter will still be within the borders of India after 20 hours, just in a slightly different location

Sir , I am your great follower. Here's a question - If only colour sensitive cells inside the human eyes are able to see the colours so , what is the actual colour of the world / universe or everything is colour less ??? Sir , please answer this 👆👆👆
It's a question of understanding of basics. What is colour? It's just due to light means em wave of a range of particular frequencies. Actual colour of world is what that we are able to see. Because colour is nothing that really exist it is because humans can sense it does not mean that it exists. There is no actual colour of world because it is refrence based.
If somehow the acceleration of both object and earth are the same . We know the force acting on both is also the same (Newton's 3rd Law ) . Therefore the mass of both the objects must have to be same to satisfy F=ma (Newton's 2nd Law ) which is not never never possible. Hence , this can be proved by contradiction method
light is electromagnetic waves it doesn't have colours in it .. then is light a mixture of waves whose wavelength are 380-450 nm ,,, 450-495 nm ,,,495-570 nm ,,,570-590 nm ,,,590-620 nm,,,620-750 nm .. as many teachers say apple appears red because it absorb all colours except red . but light do not have colours in it .. then it should absorb different waves that are in light ..but light is wave itself then how light has different waves in it

Helicopter Location on Earth.
User
If a helicopter is flew for 20 hours on stationery location at a fixed place in India, after 20 hours will it change the place as Earth rotates ?
ChatGPT
Yes, if a helicopter remains stationary at a fixed location on the surface of the Earth for 20 hours, it will change its location due to the rotation of the Earth.
The Earth completes one rotation on its axis in approximately 24 hours. Therefore, during the 20 hours the helicopter remains stationary, the Earth rotates by approximately 20/24 or 0.833 degrees. This means that the location of the helicopter on the Earth's surface will have changed by 0.833 degrees due to the Earth's rotation.
The exact distance the helicopter has moved depends on its location and the distance from the equator. The distance covered by the helicopter can be calculated using the formula:
distance = (angle in degrees) x (pi/180) x (radius of the Earth)
Assuming the helicopter is at the equator, which has a radius of approximately 6,371 kilometers, and the change in position due to the Earth's rotation is 0.833 degrees, the distance covered by the helicopter in 20 hours would be approximately:
distance = (0.833) x (pi/180) x (6,371) = 147.8 kilometers
Therefore, after 20 hours, the helicopter would have moved approximately 147.8 kilometers due to the Earth's rotation.

If a helicopter remains stationary at a fixed location in India for 20 hours, it will change its location due to the rotation of the Earth, as explained in my previous answer. However, the helicopter will still be in India after 20 hours, just in a slightly different location.
The change in the helicopter's position due to the Earth's rotation is determined by the latitude and longitude of its initial position. Assuming the helicopter is initially located at a fixed point on the ground in India, its new position after 20 hours will still be in India, just shifted slightly due to the Earth's rotation.
The exact location within India where the helicopter will end up after 20 hours depends on its initial position, as well as the latitude and longitude of that position. The change in position due to the Earth's rotation will be different for different locations within India. However, it is safe to say that the helicopter will still be within the borders of India after 20 hours, just in a slightly different location

If somehow the acceleration of both object and earth are the same . We know the force acting on both is also the same (Newton's 3rd Law ) . Therefore the mass of both the objects must have to be same to satisfy F=ma (Newton's 2nd Law ) which is not never never possible. Hence , this can be proved by contradiction method
Sir 🙏👍💯👍🙏
Nice sir ❤
Thank you so much Sir
Very good statement
Why we can identify that light is switched off or onn with our closed eyes ?........................................please tell us about that. Sir
light is electromagnetic waves it doesn't have colours in it .. then is light a mixture of waves whose wavelength are 380-450 nm ,,, 450-495 nm ,,,495-570 nm ,,,570-590 nm ,,,590-620 nm,,,620-750 nm .. as many teachers say apple appears red because it absorb all colours except red . but light do not have colours in it .. then it should absorb different waves that are in light ..but light is wave itself then how light has different waves in it
Bro apple have red pigments which make it appear red that would the reason i think!
Legend 😊
Sir different objects ka different weight Hota he means earth unhe Alag Alag Force Se khichta he to acceleration to force people depend karta he to phir acceleration due to gravity Sab objects pe constant kyu rahata he jab Unke weight different he
Science leads to sprituality
I had the same doubt in 9th standard
Sir how does light reflect from a solid opaque surface ? Kindly describe it on sub-atomic level.
Hi satwik
Savage 🔥🔥🔥
GMm/R2 hota hai to simple hai a is Gm/R2 ab since m is small acceleration is small still wo Earth ka mass pe depend nahi kar rha Sahi hai!

Thank u sir ji
Very nice sir😊
Sir my name is anshu Bhawsar, I am from mandsaur Madhyapradesh,
My Question is that as we know that there are infinite number of possible orbits (assuming circular orbits) Of a fixed radii is possible around a heavier objects in space but that shows means there are infinite number of possibilities to create whole in space time fabric but black whole creates only One agretion disk how it is possible
Sir I don't know whether my doubt is Dumb or not but I am asking still. Sir, work done in moving a charge from centre of a spherical shell is 0. Since V=W/q --> V=0 at centre according to formula but charge's potential at centre is same as that of its surface. V---> Potential 'just for info'
V is not W/q , its Energy/q and W= change in Energy so if W=0 means change in energy is 0 means energy and potential is constant.
@@tarunsuman1676 sorry did'nt get your point
Sir I have a doubt. if we say a relation is a function by vertical line method in a graph. in sin and cos graph if we increase the range means multiply with a number then graph.hight increases then we use vertical line method to define function infinite points are touching it is still a function...
The man the myth the legend 🎉🎉
Gravitational acceleration mass pe dependent krta hai agr mass bahot jyada ho to, like agr earth pe earth ke mass ke half maas ka object gir rha ho
Next month is my jee adv
Trying hard to get into iitk .
Sure i will meet you sir 😢😢
Left side 0=1 wala question लगा hai 😂😂😂😂 sir ne mitaya nhi😊
Sir's hairstyle is inspired from Isaac Newton 😅
Sir video on inertial and non-inertial frame. And why Newton's law are applicable in only inertial frame.
Mere sir bhi kaha karte hai ki kisi formula ko yaad rakhne se jyada jaruri uski conditions ko yaad rakhna hota hai
