This is really a terrific explanation. So easy to grasp.❤❤❤❤
Very good explanations on this channel. Amazing
Awesome, absolutely clear explanation 👌
Very good explanation. However the explanation to the outward push experienced by a passenger in a car taking a turn can be explained by introducing centrifugal force. The observation of the passenger sitting in a non inertial frame🎉 ( accelerating car) can be explained by introducing centrifugal force, which is in the direction opposite to the direction of the acceleration of the non inertial frame. Inertia is a qualitative way to describe this behaviour. Please respond.

as much as i understood from your comment you are saying that inertia is the qualitative way of explaining the force experienced by the particle in non inertial frame and you need the quantitative explanation of the force using centrifugal force. so I would try to explain that force quantitatively. first of all you need to understand inertia, so if you understand that then keep reading. lets start with the same example of a man inside of a car (with friction between the man and his seat being '0') moving on a circular path. So considering an instant 'T-1' when body and the car move in straight line (just like every instant in a circular motion), at another instant (say 2 seconds later) at 'T-2' the car would make a turn by rotating its tyres and hence direction of velocity of the car would change, but due to inertia of the man he would try to keep moving in the same direction and with same velocity as he was moving at T-1 so here, due to difference in direction of car and the man, the car will push the man towards the center and man's body would oppose the force applied by the car (again due to inertia:) ) and hence he would experience the force outside
Why centrifugal force on fan is also observed from ground frame
This is simplest and most understandable video on centrifugal force❤❤❤
thanks sir i was very confused with this part cause if in acclerated frame if centripetal and centrifugal cancelled each other what would be the meaning of force that we expreiece in car and if they did the maths would not make sence but by your explnation my doubts are clear
Amazing
I have fast rotating centrifuges in sugar mills used to filter crystals out to the the rotating drum.
What is the explanation for this phenomenon?
Also, it is not intuitive why friction force between car tires and road in a circular motion act toward the center?
Would it not pull the car into or toward the center?
What is the explanation for this?
Should there not be a radially outward force against which this radially inward friction force be counteracting?
Please explain, this is not intuitive.
I understand the centripetal acceleration causes center seeking force called centripetal force due to continuous change in direction of tangential velocity of the car moving in a circle.
Thanks
Can we say it is the inertia or tendency of a car in circular motion to go in a straight line tangent to the circle that is countered by the radially inward acting force of friction. between the tires and the road.
If the circular road was slippery the car would have moved away due to the inertia of the car alone the tangent and the car would have moved toward the right, but not radially outward.
Could u please verify this understanding received from your explanation. Thanks
exactly!!!
I always thought the moon has a velocity that was in a straight line and the force of gravity from the earth was the cause of it’s orbit. I am confused by the difference between centripetal and centrifugal force.
I’m guessing the particules in a density gradient centrifugation move to the outside because of their inertia too. The more dense they are, the more inertia and the more they move to the outside.
Actually yea, That is inertia of direction, That is the tendency of the object to stay in the same direction! The more the mass of the body is, the more the force required to move the body!
Sir soo why do we feel a force
While moving in circular path
because of inertia of direction
👏👏👏👏👏👏👏👏👏👏
