My jaw literally dropped at the crossover. This is all super awesome stuff!

[rileystockton]

Very entertaining and easy to watch, this coming from a student too!

[zakiwali]

You're the physics teacher everyone wishes they had

Avengers Endgame: Most ambitious crossover in history
Flipping Physics: Are you sure about that?

[galinababeshkova]

OMG! This is the best educational youtube channel ever! I find your videos so interesting, and funny! This is the definition of a creative and unique educational channel.

[EricGallant]

Watching your stuff to stay up to date on my grade twelve physics during this whole coronavirus ordeal

[nikki]

Entertaining and interesting video... First of all I hated physics subject and felt it's boring...but after watching video 😩 what to sayyy..I started loving physics....
Thank for this amazing video sir!❣️

[NicholasWatson-kk]

i made the bad decision to take AP physics before taking regular physics and your videos are helping alot

[calebmeeks]

Love your videos big fan I depend on you to help me when I have no idea what's going on in my class

[FlippingPhysics]

It would be nice if the person who translated the subtitles for this video to Arabic could let me know who you are, please?

[jacqueline.]

ahhhh this video is sooo adorable and informative! thank you!!!

[Ren-gcnq]

thank you for making science so entertaining and comedic XD and thank you for this video, i was hoping to find elastic potential energy introduction thats easy to get bec. the others are quite complicated. Hope you make more videos! :)

[joshuayoon]

Loved it! Wish I had these last year when I was prepping for the Physics 1 exam. Wish you had Physics 2 lectures as well :'(

Tnx man awsome learning method
From Algeria 😘

[angelcambarijan]

Is spring constant and force constant the same?

[danamoldovan]

"Bobby, Would you mind doing that for us?"
"Sure."
"Thanks!" 5:06

Awesome channel, and even more awesome person!!!

Kinetic energy for a freely falling object

When an object is positioned at a certain height, it must have a certain amount of potential energy.
If this block is allowed to descend freely due to gravity's acceleration, the object's potential energy can be converted to kinetic energy.
The mass of the object, its acceleration owing to gravity, and the height at which it is put determine the potential energy of the object.
The kinetic energy of an object is determined by the mass of the thing and the velocity at which it is traveling.
When an object falls from a certain height, the object's potential energy reduces but its kinetic energy increases.
The complete potential energy of the object is transformed to kinetic energy at the moment it reaches the ground.
When an object collides with the ground, its kinetic energy is transformed into heat and sound energy, which is why sound is produced when it falls to the earth.
Hence, when an object falls freely, its potential energy gets converted into kinetic energy. When the object hits the ground, its kinetic energy gets converted into heat energy and sound energy.

what about from -.5 back to 0? i did it, i cant remember how.

Use spring of ⏰ so we found the total energy storage in it and we use it in many ways like hydraulic and electricity to recharge our car battery 🔋
And trimmer and so on
