Understanding Circular Motion

This video presents a beginner's guide to circular motion, introducing the concept of centripetal force. It also briefly discusses the erroneous term centrifugal force. It also explains the motion with some common examples. 

CLARIFICATION: in the video I mention that 'there is no centrifugal force"
What I mean is, there is no centrifugal force acting on the object spinning, like some outward force acting on the object. This is fictitious.
In the specific case of a car going around the bend, the centripetal force is provided by the road surface on the car, going inward
One could argue the centrifugal force is the force on the road by the car, which is the reaction force based on 3rd law.

Excellent explanation and very understandable!
Really helped with learning from home due to Covid

[mokhalif]

this is amazing lecture sir keep it up doing such useful tutorials on physics

[Miragedeluded]

I troubled with the concept of banking of road. thank you so much for your fantastic explanation

[hanif]

thank you so much bro for your amazing works
all your videos are very enlightening

[MasterSkywalker.]

You deserve more audience. Keep it up. Upload more content sir

[afiyaparveen]

Thank you so much sir, amazing explanation

ok, that was great, now let me ask you a question: we know that an object always moves in the direction of resultant force - if two tractors moving at an angle of 45 from each other and pulling a mass, the mass will move forward at an angle 22.5 to either of them. Now when a car is moving in a straight line, the resultant force is that of engine E in forward direction. but as soon as we turn the steering wheel, the friction force F start to act at 90 to the E. F is not equal to E but relatively small and dependent on tires etc. so when F & E are added, we get resultant force (say) G which acts on the car at some angle lesser than 90 and the car moves in its direction. So we can say that the car is accelerating in the direction of this resultant force and not towards the center of circle of the bank of the road.

I was distracted before your irrelevant material
By the beautiful Act of the human itself
You put a beautiful concept in putting the circle together
? It takes a character of Ingenuity to balance One Professional view of this
Wild and out Simply will not work
The sequence to this motion is being controlled
And so many inner thoughts
As we come down to its shaft or where your hands meet..
I'm sorry
I'm going off the circle
Want to use cubes

oh wow this was helpful, thank you so much.

So, if I had a mass and it is spinning from top to bottom/vertically and that same mass is also spinning horizontally. What would happen to that mass if one just lets it spin freely? Would the centripetal force still be towards the center, I would think so. Please don't tell me that this is not impossible because I have devised a mechanism that does just that. But, it is not finished as of yet. I just need the ICs to finish it off. What would happen to this object as far as trajectory is concerned?

Connect a string to a motionless mass .
A pull on that string causes the object to move in the direction of the pull.
Of course a force at 90 degree angle to the string CAN NOT be applied by pulling on the string !

In order to get that object START to move on a circular motion, the right angles force must be applied by some
external means.
ONLY AFTER this right angle force is applied will the object move at right angles to the string

I have a very simple but intuitive question.
Why doesnt the object collapse into the point.
Since the centripetal force is an acceleration is increasing with time it should get to a point where its high enough to pull the object towards its centre.
For example:
The electron in an atom if not for its stationary state it should be pulled towards the nucleus since the proton and nucleus attract but what keeps it moving in a circular path is the fact that they have fixed energy called stationary States so they can't lose energy.
But objects in the real world dont have fixed energy level so what keeps them in circular path?

Another example is that if we change the mechanics occurring on the body interns of force, The centripetal force will be the F=m×a but converting the objects tangential velocity into force its F=0 since it has no acceleration.Resolving the 2 forces the object is supposed to move towards the center so why does it still moves circular

[mohamadfazli]

But you didn't explain why you use square velicty, why not kust single velicity, can you explain ?

[zmaxproductionsharry]

You would of already explaied but I am forgetful sorry, what actually stops the object being pulled towards the centre by the centripetal force. I understand with a string, with tension and all that but I don't understand when the object isn't physically attached to the middle of the circle (Like a guy spinning a ball on a string)

[Lovecovenant]

Beautiful tutorial sir but about the centrifugal force part
My text book says that according to Newton's third law of motion there's and equal and oppositely directed force on the body called centrifugal force

[anmirfan]

I have a few questions,
u said there’s change in velocity every direction due to the force, however the force and distance towards the force is same at every point so why the change in velocity, and no pls don’t reply with velocity is change in direction that’s why, it doesn’t make sense.
One more thing when taking acceleration of circular motion we do speed upon time when mathematically acceleration is velocity upon time and velocity is displacement upon time so if do if we do velocity upon time then since displacement is 0, (displacement is shortest distance ) we find it will be 0 decided by time making 0 and that’s why acc should be 0 too

A merry go round horse is encircling the ride at a speed of 6 m/s. If the diameter of the ride is 18.64 m, how much force is the horse exerting, provided that its mass is 152 kg?


Can someone help me with this

[sunflowerflower]

Idk why but my brain is making up questions about this topic and I have been looking everywhere to answer the questions in my brain but I don’t seem to find the right YT video 😕😭

Here I create 24 million G's from centripetal force @
