Can u make a video about Newton's laws and how calculate it's resultant and all that please

[@chheamsolita6025]

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.

Best explanantion ever

[@tangcherry1272]

Thank you so much! You explained very clearly!

[@torgalski3368]

This is a very interesting topic and I enjoyed this! I’m in 7th grade also so it made this cool to learn

[@dilipchavan5236]

U r the best....lots of love from INDIA

[@virupannamedikinal]

Thank you so much

[@jordan_46k]

The video was very helpful !!!!!! Thanks

[@MulugetaNigate]

This akinda interesting.keep it up

[@BrandonAmaro]

would the tension in 1 & 2 be 15 [n] distributed equally on both T1 and T2

[@enochkandiah6445]

thank you

[@tanmayking3252]

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?

[@neiljostensgf]

the normal force would technically be the force of the block and gravity would still be there

[@lorenzoemanueletomasello215]

Great!

[@bread3776]

Thanks! This really helped!! ❤️

[@rajvichandra5373]

good

[@toddrathier5263]

What software are you using for the whiteboard (or blackboard) effect?

[@armstrongtixid6873]

Yeah, I am interested.

[@Jakppsjsjs]

It is called Smoothdraw 3 :)

[@kalpanasuneel-kk7bu]

What about sin and cosine in FBD

[@flawedhumanity]

What is free body diagram actually?

[@Mster_J]

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

[@jenngzz11]

Oh noo! I needed this video to be way longer.

[@Hobbit183]

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

[@carcinogenicthalidomide3057]

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.

[@Hobbit183]

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?

[@carcinogenicthalidomide3057]

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.

Jai hind

[@balakrishnanvijayaraghavan9697]

any one from nios

[@studysimple6364]

Because I think that most of ur viewer in an indian

[@studysimple6364]

Sir upload video on kinematics (full lecture). And please sir try to speak in hindi. Explain clearly okh

[@sonamgupta2142]

Actually he is not indian
