I really like the way you break everything down. Sometimes, you just need to know the practical calculation first before really getting into the theory... at least for me. I get more confused if it's the other way around

SAME. I need an actual practical of the theory right away I can’t understand the theory by just it’s definition, linking it to reality to see the bigger picture helps me.

I am currently studying a course in mechanisc. These videos are near identical to the problems I've been trying to solve. We don't get much in the way of material so we got to teach ourselves. Thank you "The Organic Chemistry Tutor" you are awesome!

Sir, all of your videos is really a help specially in engineering students, keep it up sir😎😎😎😎

You make this so simple! Thank you... I love your instructional videos

I’ve spent a whole semester listening to my teacher and I haven’t understood anything. Thank god for this channel honestly. 🙌🏻🙌🏻

i can't thank you enough! the organic chem tutor explains everything so clearly and im glad the concept is clear in my head now you saved my life lol

thank you very much. I hope i can remember verything for the quiz tomm. thanks again lifesaver

Thank you for this! I'm really having a hard time answering 1 of my homework and I need a reference to know how to solve this kind of problem and luckily it's in this video! again I wanna say thank you for this your videos are so helpful for someone who suck at Physics

You're the hero in life I needed.

Oh wow, he explained it pretty well

You explained them very well sir. I have been trying to understand from books but they don't make much sense and are very big. So thanks a lot

THANK YOU SO MUCH THIS SAVED ME BEFORE MY MIDTERM

Very well done, very helpful

It's really help me Sir thanks from India.😃😃

I salute you Dr------------- kept it up with the good work

Posted on my birthday from 2 years ago!

Thank you bro,I like your channel.You always help me 😁

I just finished a physics lab and because of this I got it right!! It took me so long but when I did, I couldn't tell you the joy and satisfaction that it brought. THANKSSSSSS 😭😭😭

life saving ! thank u 😍😍😍

Sir you are too good please upload more videos sir I am just your fan from the only video that I watched and that is this

Your videos have helped me a lot this semester, have you done a problem with an inelastic collision in one dimension on a incline. for example a box on a 7/12 pitch roof and a squirrel running jumps on it and it slides down the roof. How do you figure out where it will land on the ground.

WE ALL LOVE YOU SIR!!❤️

A good man, be him. A physics student's messiah.

beautiful physics ..u helping a lot

How do you find the distance of two cars that collided together? You have the mass and the speeds of both cars

Ir really accept you as the top teacher in the world may you live long

I'm taking pure science in 11 grade and this vedio is very helpful wish to watch more Vedios from you may God bless you

thanks for the help appreciate it!

Crystal clear 👌 ✨️

Thanks, this really helped me

Thank you very much sir for this lesson

Question on the number 3 M1 is the mass of the bullet V1 is the speed of the bullet So why the m1v1' turn out into the Mass and the speed of the block and the m2v2' turn out mass and speed of the bullet?

10QU! so much really you are a good teacher for me!!

Thank you once again.

In the last example, why was your m1 in the final momentum the mass of the block? While the m1 in your initial momentum is the mass of the bullet?

Thanks for the help :).

These videos are great but I do have one small suggestion. If you edited out some of the gaps between speech it would make it a little easier to listen to. I tried playing the video at a higher speed but the problem is not the tempo of the actual speech itself the problem is the amount of time in between. I find it difficult to pay attention.

THIS IS REALLY HELPFULLLL 😭😭😭

for question 3 isnt m1 for the bullet and m2 for the block ? ,, do we interchange it for after the collision ?

Bro I just saved me from failing the midterm so easy thx bruh

tysm you helped a lot

Very nice explanation;

How do you find the initial velocity of the bullet before the collision when given the mass of the bullet and the mass of the block, the height of a table that the block is resting on and the distance the bullet and block travel after the collision?

Thank you Sir Gonzalez

plz make a video on physical optics & Coordination chemistry

you saved my life.

In the 2nd problem shouldn't it be the change in kinetic energy which is equal to the gain in gpe

4:30 but isn’t the height dependent on the length of the string? For example, if the length of the string was 1000m it will rise less than if it was 10cm.

I think the initial high would be assumed to be at level 0, so went it is hit; and rises, then the high is positive.

In the 1st part of 2nd question why he didnt put the value of M2 in the formula of inelastic collision but a 0 WHY?please tell me

What if two objects moving in different directions collide and stick together, how do you calculate that?

please help me with this one A bullet mass of 0.005kg is fired with horizontally into a wooden block of mass of 1.2kg which is resting on a horizontal surface.The cofficient of kinetic energy is between block and the surface is 0.20 .The bullet remains embedded in the block and the block is observed to have moved 0.230 m along the surface before stopping.Calculate intial velocity of the bullet

8:04 are they not different masses? great video.

ty sm :)))

Make the velocity of block 2 to be 20 m/s. Show the math that illustrates the problem with this.

You're the only hope Sir😥

If a 10kg mass object with a speed 27.77m/s and an opposit object with the same mass and speed what will happen after collision ???

Hey mn the masses are different not the same because kinetic energy is only related to the bullet and potential energy is related to both the bullet and the block

Where does the lost kinetic energy go? Everyone says it becomes other kinds of energy such as thermal but I think that it is also lost in chaging the objects' momentum.

Could someone please answer this for me I’ve tried solving tons of times but I keep getting confused Q: A 5g bullet is fired horizontally and hits an 8kg block of wood (initially at rest) which can move freely. The wood and the bullet move with a velocity of 0.50 m/s after impact. What is the initial velocity of the bullet?

@annastein1128

Assuming an inelastic collision, m1v1+m2v2 (momentum of bullet and momentum of block) = (m1+m2)v3 (momentum of the bullet block system). Plugging in all values we get 0.005*v1 + 8*0 = (8.005)(0.5) And get a final result of v1 = 800.5 m/s

@KRATOS-dq6sd

3 жыл бұрын

We can use conservation of momentum here which states that m1u1+m2u2=m1v1+m2v2 So initial momentum of the block is 0 as it asrest as mentioned Since they are moving together 0.05u1= 0.05+8*0.50 which gives 8.05m/s

I LOVE YOU DUDE

This is a good video, however I would suggest an improvement: Solve equations algebraically before plugging in values.

so im a bit confused, why did you 1.5 as final velocity for mass 1 and 0.025 for mass 2, at 11:14

@@meganrivera7653 Yes, but the masses are switched at the end. He uses M1 as 0.025 and then uses it for M2. Which is confusing because that would mean V1 initial equals V2 final.

thx for the help my teacher is wack

how m2v2 is 0?

2:49 Wrong! True equation must be (m1 + m2) * Vf.
