- In this video David shows how the area under a Force vs. position graph equals the work done by the force and solves some sample problems.

Physics on Khan Academy: Physics is the study of the basic principles that govern the physical world around us. We'll start by looking at motion itself. Then, we'll learn about forces, momentum, energy, and other concepts in lots of different physical situations. To get the most out of physics, you'll need a solid understanding of algebra and a basic understanding of trigonometry.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

11:12 ". . .this ramp has no friction, but Walter has no fear." That's moving.
Walter is a weird penguin he slides on his back
R3V 69 so you slide on ur belly?
@@candyyatliu9736 what do u slide on?
what is your problum
I thought the same thing. Penguins slide on their bellies.
Why he slide on his back 😅😅😅😅😅
this one blew my mind - I got instantly smarter in
that one dislike is from Walter who disagrees that he's bored in Antarctica
now its 4 dislikes! I bet Walter told his friends that the guy made fun of him by making him sliding on his back, they will form penguin army and soon all the penguins in the world will dislike, PeNgUiNs HaVe EnTeReD ThE ChAt
@@miniusss nope its WALTERS.... maybe even human who named walter and other living organism too
@@WayneCXT99 :O, thats a reasonable answer!
im not really sure of this but i guess in the final example u gave ; the angle of the incline platforme from where the walter slides metter too , because standing there means the the weight P ecuals mg * cos alpha which alpha is the angle of the incline platfome and h ecuals zero because he is standing on it
i had the same question pro.
Awesome man
Thanks for this video
Good video.
I propose a problem similar with four sub chapters :
walter and friends at play : how fast walter must throw a snowball to be happens follow phenomenon
1. a snowball melt in flight /
2. a snowball vaporize in flight /
3. a snowball melt on impact with the target (fixed building wall)
4. a snowball vaporize on impact with the target (fixed immobile wall).
the coefficient of friction with the air is u being constant and the atmospheric density r is also constant
whole "secrete " of this problem is where put u (friction coefficient) in the equation Et = (mv ^ 2) + mgh ...
I loved this one ❤
Can you describe the thermal energy in terms of a type of Potential energy?
Any time I see KE, I think of the conversion of KE to PE.
Thank you
This make my mind fresh
he slide on back this is so funny
Mind = Blown
Can you explain me thermal energy?
Are you watching this video because
A: You searched it up
B: The school made you watch it
C: This showed it in your suggestion results
A.
A as well
Penguins are smart :)
Thanks for the video!
Who came here to prove that you can cook a chicken by slapping it?
Not me 🤣🤣...
take a shot every time this guy says feathery coat~
"System"

What you right we can't see anything that you right

walter is my goat
