Really helpful thanks man

[@AR-op7lc]

Thank you sooooo much. I'm really grateful, now I really understand

[@TheScienceClassroom]

Way to go! I'm glad this video helped! 😀

[@hayelmhanna6179]

thx u explained well

[@blessingskashita5078]

Wow thank you you are helping us alot

[@TheScienceClassroom]

You're welcome! 🙂

[@narutoball_3556]

great moves keep it up

[@ellen-rd3nn]

haha h3

[@apfelsafteis]

So I was told that work input and output have to be the same. Is that not true?

[@mrcat5529]

Equal action to the reaction?

[@DrNavarrio]

Hey nice video its paul from your first hour

[@mkoerber44]

Hey Paul from first hour

THANKYOU

[@maryyuan9747]

The input force should be input work around 5:10

Thank you so much 100 percent efficient 😂

Thank you I almost failed this class

[@mrcat5529]

Please what does MA and VR stand for.. is it milliamps and velocity ratio

[@TheEliteAryan]

MA stands for mechanical advantage
VR i dont know sorry

[@tahayousaf3275]

VR is Velocity Ratio

[@mrcat5529]

Thank you gents x

[@dynamicmonik8733]

Nice

[@tutorialkinggames269]

my teacher sent me here

Same lol

he is meh science teacher

[@eastonboggs5520]

cool beans

[@jasonaliwala1527]

I skipped 6 pages of notes that probably won’t make sense to me for an 8 minute video that I can fully understand

[@YNGSMOKE]

Thank u very much lmao

[@marcamoo8122]

RAPPER!

[@YNGSMOKE]

MarcAMOO yea but I still gotta do school 😂

[@Olduser911]

​@@marcamoo8122 chill 😂😂 I read that wrong

[@user-zq3bq7jk3r]

Best but improve it to got better view 😊😊😊

[@renehincapie6818]

Maybe I don't understand something. Following your formula with a more inclined plane you do the lifting easier, but it is less efficient???? I have read that efficiency let you do the same work with less effort. Then, more inclined is the plane more efficiency.

[@TheScienceClassroom]

An inclined plane will require less force than to lift the object straight up. It's not necessarily less work because you have to also consider the distance to move the object, which is always more when using an inclined plane.

[@RaptorRapine]

I came here from my teacher lol

[@idkanymore9590]

Same here lol

[@okegbenromustekeem7845]

Nice one👍, but always try to speak loud than this sir

[@okegbenromustekeem7845]

Louder than this sir*
