What about the forces acting on the surface of a table (say )with a block on it *normal reaction in downward direction (due to electrostatic interactions) *But why not the force of weight of the block?
If I get what you are asking it is just a representation of an object and the forces acting upon it which you would draw with arrows in the direction that they are acting on the object
Normal force is a contact force.Acts usually when a body tries to push something.For example:the force we feel when we push a wall,acts normal to the force(push) u apply on a wall.
i know it acts normal to the object but exactly where on the object. for example if you pull hard on the box it might start to slip but it could also rotate and flip over. i mean in order for an object to be in static equillibrium the sum of the moments at some fixed point and the sum of forces must be zero. so where should the normal force be placed on the object so that the sum of the moments is zero too?
Fredde I think u r making it too complex, it's too good to be practical but it's not,when u are introduced to new terms. Usually,in physics there are many assumptions to be taken into consideration and most of don't need to be reminded of that. Now, talking about origin of forces, conceptually it's okay to understand that the origin of a force say Weight is from the com of the body but fbd gives u the freedom of drawing just the forces acting on a body.Talking about normal force it boils down to molecular level but it's not required to understand the concept of normal force.I don't know how to explain since I'm not familiar with the American education system and how previous concepts have been fed to you.Talking about sum of moments it maintains a body in equilibrium given it sums to zero or else it produces a moment.
Best explanantion ever
This is a very interesting topic and I enjoyed this! I’m in 7th grade also so it made this cool to learn
Can u make a video about Newton's laws and how calculate it's resultant and all that please
You can search through Google in page Khan academy because I ever checked it. And I can see the laws of new ton there too.
Thank you so much! You explained very clearly!
U r the best....lots of love from INDIA
would the tension in 1 & 2 be 15 [n] distributed equally on both T1 and T2
Thank you so much
The video was very helpful !!!!!! Thanks
This akinda interesting.keep it up
thank you
Great!
Thanks! This really helped!! ❤️
What software are you using for the whiteboard (or blackboard) effect?
Yeah, I am interested.
It is called Smoothdraw 3 :)
What about the forces acting on the surface of a table (say )with a block on it
*normal reaction in downward direction (due to electrostatic interactions)
*But why not the force of weight of the block?
the normal force would technically be the force of the block and gravity would still be there
good
What about sin and cosine in FBD
Oh noo! I needed this video to be way longer.
What is free body diagram actually?
If I get what you are asking it is just a representation of an object and the forces acting upon it which you would draw with arrows in the direction that they are acting on the object
But where on the object does the normalforce act? Since its in equillibrium the sum of moments, for example at the center of mass , must be zero

Towards the open sky
Jai hind
any one from nios
Because I think that most of ur viewer in an indian
Sir upload video on kinematics (full lecture). And please sir try to speak in hindi. Explain clearly okh
Actually he is not indian
