Energy, Work & Power (19 of 31) Conservation of Mechanical Energy, An Explanation

In this video Mr. Swarthout explains total mechanical energy and how you can use it in together with conservation of energy to solve problems in physics.

In the example shown in this video, work is done on the object to raise the object to a specific height. At its greatest height, before it is released, it is at rest and has no kinetic energy but has its greatest amount of potential energy. When it is allowed to fall back down the objects potential energy is converted to kinetic energy. Just before it reaches the bottom the object will have reached its greatest velocity. All of its potential energy has been converted to kinetic energy. Therefore, it will have no potential energy but it will have its greatest kinetic energy.

better than what my physics professor explains for 3 hours. Thank You.

[jim-anant]

Wow better than I explained to my students. Quality content like yours is always appreciated Sir!

[Amberischewyy]

So grateful! Makes me realize physics isn't as difficult as I imagined.

[edwinanthony]

wow, you make everything simpler than how my teacher explains.
I love your channel it helps me get through physics. thank you for existing <3

[mahnoordurrani]

Thank you so much all my concepts on the conservation of mechanical energy have been cleared

[hassanulger]

The way you explained it was legendary!

[daniloorbolato]

Your videos are awesome. very helpful. Exam in a week. Wish me luck! 😀

[fatimaalhawaj]

This video saved my grades thank you so much

[angelakate]

My physics professor give this reference to us and I'm happy i am able to understand this

[japjeetsuden]

hi, could I ask something, which you might not be able to do because of time, and I totally get that.
Is there any way you could add captions on these? Because I have some hearings issues and some of the stuff you're saying gets oddly translated in the auto-generated English subtitles.
Cheers!

[PhoenixQueen]

Thanks. I have a test tomorrow, and I needed this.

[kawaeeee]

little confuse.... If Ui at rest, U=mg*change of y, the y should be zero? because there have nothing change in height. and when it fall, the y should be -5?

[ealhejaily]

Thank you very much for those great videos. I would suggest though that you put this work/energy videos in a series like other videos by you. Example: simple machines (1/7 video series) motions videos (1/21 video series), etc... great work though!

[riyadbushnaq]

Thank you so much :), you really made it clear for viewers. Great job

[luwaarosina]

Thanks very much, it was very helpfull and think you deserve more thumbs ….we are patiently waiting for more and well explained as well.

[layanas]

your lessons are really helping me in my studies thank you 

[ziarazonable]

Thanks im only in 8th grade . This is our lesson . And i got it .. thank you very much❤

[Mrbonehunter]

this is a lot of help for me thank you so much

[MJbrrr]

I did an exam question of my board
In order to find distance traveled
They have used kinetic energy = gravitational potential energy + work done
Is this wrong

[oscarduran]

Where does the energy go when it hits the ground and stops moving
