Kinetic Energy and Potential Energy

You can put energy into an object. Wanna know how? No, you don't need a Harry Potter wand. Just lift it up above your head! By doing so, you bestow the object with more potential energy. Learn more about the energy of motion and the energy of location in this clip.

Here I am studying MSc in Engineering but watching this rather simple video I guess I needed something as simple and clear as this video after being lost in the details, something like this reminds you of the essence of these basic concepts.
It's not a shame to go over these simple terms (other simple terms also) every once and a while as I get some sort of refreshness and a slight smile of how things were nice and simple.
Great video, thank you.

I dont know if anyone has noticed but Professor Dave seems to know a lot about the science stuff. All jokes aside our videos are really helpful and I watch them every time we learn a new unit in physics.

Professor Dave. You are frik'n smart man. Thank you for sharing this video on YouTube. You're the best!

[purplestacks]

I use to hate ur intro and the way you explain things. Lately I've been realizing that you are proficient when it comes to concepts especially when it comes to physics. Keep this subscription forever and I hope you continue uploading videos. Thank you for helping an electronics engineering student who is so terrible at physics.

I did it by other method
First I found k.E
1/2×50×11.2×11.2=3136J
As it transfers 1539J to another body so 3136-1539=1597J
So new kE is 1597J
1/2mv^2=1597
1/2×50×v^2=1597 ( as mass is given 50)
25v^2=1597
V^2=1597/25
V^2=63.88
V=7.99

im watching this in 2020 and this rlly helped me. I love ur intro! <3

If I'll ever feel useless, I'll remember there's people who dislikes this video

Proffersor dave, thank you, I had a difficult time answering this question "in a frictionless enviroment, would an object of heavier mass have greater ke than a lighter mass?" until I watched this vid. Wish you the best in your future endeavours.

2022 and still helpfull !!! The content he teaches in under 5 mins is just awesome ! Loved it ❤

[heythere]

Wow !
You defined potential energy quite perfect .

[dkwhattouseasusername]

Just discovered this channel but wow, really good, his explanations are simple and easy to understand

I remember when I was a kid jumping on my trampoline I’d take my mums keys and let them go as I was coming up or falling back down but what supprised me (besides the fact that the keys and I fell at the same speed) was that when I let them go as I was coming up they would go higher then me but then still fall at the same speed, back then I didn’t know what gravity was or that things fell at the same speed but it was so mesmerising letting go of the keys because they’d kind of just move in slow motion as they were faking

[kyuu]

I feel so proud of myself actually getting the practice problem right lol. Thank you so much!

[ilyverse]

THANK YOU SO MUCH! I HAVE TO WRITE AN ESSAY ABOUT POTENTIAL AND KINETIC ENERGY AND THIS HAS HELPED ME A LOT :)

[swagdork]

the intro was like a primary school teacher and then he starts bamboozling my brain

[MrMarkgyuro]

just understood, thank you Professor! I have realised it is called potential because it is potential.

[sarinayaghoobian]

This man taught me in 4 mins what my science teacher couldn’t teach me in 4 months

[myprofilepictureisbeberexha]

Thanks Professer my school teacher showed us the video and it helps me alot.

Since the start of online classes, some teachers are not at all efficient in explaining this. ARIGATO GOZAIMASU DAVE

Your video was short and helpful compare to other videos. I kinda got the material gradually. When I do the problem, I almost got it except the negative signs.
I wonder why is negative ?
