Lets talk about levers, and how we use these levers in everyday life and inside our bodies to produce movement, increase force, and make directional changes. Levers are one of the simplest forms of a machine.
A lever is a simple machine that allows you to gain a mechanical advantage in moving an object or in applying a force to an object. there are 3 classes of levers, The 1st class lever, 2nd class lever, and 3rd class lever.
A lever is a simple machine that consists of 4 parts
The 1st part is The Fulcrum, known as the pivot point, axis, or balance point,
The 2nd part is the Resistance or load
The 3rd part is the Effort Force
The 4th part is the Lever Arm…. which can be divided into 2 parts, the Force Arm and The resistance arm.
Now the main function of a lever is to gain a mechanical advantage in moving an object or gaining force. Mathematically, the mechanical advantage is determined by dividing the Force Arm by the resistance arm.

I’ve spent like 2 whole hours trying to understand this and all it finally took was this video thanks bro
This was such a great example of levers! I always struggle to remember them, but your "FRE" mnemonic was really helpful! Thank you!
Definitely a game changer!
daddy kris coming in with the lever vid 😫😫
This is so precise,clear and easy to understand,the only video on youtube thats digestible to me on this matter. Thankyou!
Thank you so much for your kind words. I put alot of effort I to this video, so it means alot. Now if ai could just get off my butt and make some more....lol.
Thank u very much this was soo helpful ❤❤❤❤❤❤❤
Glad it was helpful!
Amazing info!!!
Soooo helpfulll!! Thank you for this video!!
I totally didn’t just understand a difficult topic in a 6 minutes video the night before my test--
Great video bro! 👍
You got this! Hope you
Aced that test Bro! Thanks for the awesome comment
I can't thank you enough! Saved me before the midterm.
Thank you!
GOOD JOB!!!!!!!!!!!!!!!!
Thanks for the fre tip!!!
NOICE, THANK YOU SIR!
Thanks a lot
Not watching for kinesiology but your video was concise and memorable, and is way better at explaining than my course. Thanks!
Great video! Very helpful!
Glad it was helpful!
Wow thank you so much guys
My pleasure, Thanks for watching
So helpful!
So glad!
@@KinesiologyKriswhere did you go?
Mr Kris this video is awesome and it helped me understand levers more
I'm glad it helped you! Thanks for the lovely comment 🙏
Thank you!!
You're welcome!
Not me learning levers in 6 minutes a night before an exam and understanding it because of you 👀❤️
Thank you so much for the feedback, I'm glad you liked it. Made it worth making!
I can't understand a thing he's talking
😍
What kind of exam?
Thank you so much! This has helped me in my study of anatomy!
This was very useful for my test tomorrow
I wish you the best of luck on your test
wow you have great tips and learning techniques !
Do we use this as a variable to program/design exercises or is this relevant to an exam only?
This is just to learn about levers for an exam or just to learn the 3 classes of levers. I'd definitely not use anything I say to program an exercise. You give me to much credit. I'm a dumb dumb 🤪 . Which is why I try to help other dumb dumbs understand concepts 💡
@@KinesiologyKris hahaha. Actually, the reason why I had asked you is because I'm preparing for my ACSM CPT exam and this topic had come up. For a moment it feels like I understood the concept and then the next moment it's totally destroyed.
Assalamualaikum,
Very good info i was just preparing for my grade 7 online quiz ;) great helped me so much keep it up!
I'm glad that it helped you! Thank you! For commenting
This is a good example of levers my son had trouble doing it and he now understands thank you
. .
O cool
Great explanation! Nice video.
Glad you liked it!
This is better than tedtalk! Thank you
This because it's a Kris Talk! 😆. Thank you very much!
Amazing video the teacher explains this for hour or more yet 6 minutes (of hard work) and great animations in fully confident in it now, thank you
Wow, thanks!
Thank you- Also why do you get all the ladies?
Very good information all around
Glad you liked it
Thank you sir
You teach very nicely...great teacher you are
It's my pleasure
you make learning fun. thanks
I say you don't fully understand something until you can simplify it... you've mastered this! Thank you.
Super helpful thanks a lot
(The lever part was funny but a very bold move in 2020 with all of the tension going around still enjoyed it though)
Yes I considered changing it because of the formentioned tension. But if we keep going the direction society is going... soon we won't be able to joke about anything. People just need to relax alottle and enjoy the day . Thank you for the lovely comment and feedback.
@@KinesiologyKris Thanks for the video and thanks for not changing that part!
Thank you it helps a lot
You're Welcome! Glad that you enjoyed it.
It’s to soon to say I love you 😘 thank you
Before watching this video I had no idea what levers were. Now after the Patty McFatty & Skinny Sara example I completely understand it 😂
I'm glad Patty and Sara could help you.
Awesome video 👌
Thank you!
Why is the second class lever is least abundant in human body inspite of it’s mechanical advantage?
Thats a question between you and god, LOL..
Perfect. :) Thanks!
Thank you for simplifying the material . 🙏🏿
this was helpful:) ty
seriously best explaination
Glad that you liked it!!
Thanks bro i appreciate it
The most liked comment please
Your very welcome! Thanks for commenting.
Nice tip for remembering the types! Keep it up!
great video
Thanks!
I owe u tbh
two years of off and on trying to learn the levers....this guy teaches me it in 6 minutes.....
This comment means so much man! Thank you. I literally put in 30-40 hours into making this video and the best way to present it. So it is greatly appreciated when people express appreciation for the hard work.
@@KinesiologyKris I'm in the same situation he was in. Thanks for an awesome video!

Very helpful
Glad it helped
Thank you
You are welcome! Thank you for commenting! ❤🖤❤🖤
Thank you so much
Thank you for explaining us in the simple way...
Thank you sir
Why was the third one so much shorter
But overall great vid also was very helpful
You saved me before my exams thank you
Thank you thank you thank you
You're welcome. You're Welcome. You're welcome. :-)
Thats where my oreos went!
Yes, Patty got them all!
A year later and this is still clutch
I have a Q’s what does the number on the 1 > 2
2 is greater than 1.. 1< 2...... 3 is less than 4... 4 > 3...
1 is not greater than 2.... it should be written 1 < 2..
Legend are watching after 1year
Sebastian Manascalco with the physics, OH!
this guys got comedy gold
This guy sounds like luke thenotable
searched the guy and I guess I see what your talking about... a little bit... but let's be honest, my voice is hotter :-)
great video but you gotta drop the schitk
Kinda hard to believe this was made this year knowing how buthurt people get about weight jokes lol
Ya, I considered not doing it just for that reason, had to double think the whole Patty Mcfatty thing. But I dont thinknits that bad. I'm sure ill get a complaint eventually.
@@KinesiologyKris I think it was kind of unnecessary (and incorrect as weight is not simply determined by what you eat, and this is a science video!). You could have used a kid playing with his/her parent or a friend having an early growth spurt. Really good explanation otherwise!!
@@MaytalMichelle He isn't scientifically incorrect about what food choices may lead to an individual towards obesity. Typically, the sweets (like Oreo's) are more calorie dense, and easier to over consume due to their higher palatability. Dipping them in grease (which is mostly pure fat which is 9 kiliocalories per 1g verses less calorie dense macronutriets such as carbohydrates and proteins that only yield 4 kilocalories per 1g.) Vegetables are extremely low calorie dense foods, with higher total volume. This mean you could fill your stomach with more (by volume) greens and veggies for less calories than Oreo's dipped in grease. At the end of the day, the laws of thermodynamics will always apply. You eat more energy (represented as kilocalories) than you expend, your body stores this excess as body fat.
@tank hurl Thank you for saying this 😀. Sometimes you just have to nood your head and agree, with a commenter. When actually you're in complete disagreement. But you don't want to start a Troll train.
@@MaytalMichelle poor thing. :( always someone to say something lol
Eminim rapping sounds like :
Good description though not politically correct by introducing Patty McFatty and a fart. If Skinny Sara eats enough beans she will fart far more than Patty. To be fair.
Lol 🤣
a lever is a BLOOOP!!! that gives us BLOOP!!!! PLOOOP!!!! mechanical adva... CRASH!!! BLOOOOP!!!!!!! PPOOOOOPPPPP!!!!!
thanks anyway 😅
oof im here for school
Schooooolllllll! is Coooolll
this guys voice grates on my nerves, and he misspelt advantage in the first like, minute of the vid
Thank you 😊 for watching , Sorry my voice sucks! And I'll try harder not to misspell anything in the future. Thanks for the feedback!
Unprofessional standards using childish cartoon sounds.. SSSSSSWWWWWWWIIIIIISSSSSSHHHH / ZZZZZAAAAAAAPPPP to the dislike button jr
so helpful!!
Glad that it helped you!
