PS2A - Forces and Motion

[@Bozemanscience1]

I use Keynote (a Mac alternative to Powerpoint) for the presentation and animations. The magic move transition workds great.

I love you, your so brilliant

So smart🍎

In the formula F=ma, a has a time variable which means F = 0 when time = 0 and Force can not be calculated unless you provide time duration. The parameter a Acceleration is due to the Gravity and Gravity has a set vector / direction, 0 to 180 degree, in other words there is NO Acceleration if there is NO Gravity, and in Gravity direction and Time needed. Force is 0 (zero) unless you give a non zero time.This is what scientists have been hiding and the space time scam is to explain a flawed formula using the gang leader einstein. E=mc2 is also False since you can change the constant 2 to 3 or any other number, it has no effect because E has no Unit. Also all the formulas mentioned as the successor to E=mc2, has the Time variable with the value 0 (zero) which makes all the calculated Forces, Energies and Vectors Zero. Additionally einstein never wrote and published any of these formulas and no other scientist wanted to claim Fallacy.

Awesome, well-spoken explanation... thank you. I'm studying physics for game development and it's amazing how many possibilities open up once you understand it

[@kikogamez8822]

this is a good video about the 3 laws of newton.

[@Descendants_Girl-m22]

Thank you for helping me by making this video

At 3:17, this is a misleading trope, that the gravity pulling down on the book is an action force and the reaction force is the Normal Force holding up the book. That would mean the action and reaction forces act on ONLY the book. And if that's true of all forces, that a reaction force always acts on the SAME object and is equal and opposite, NO CHANGE IN MOTION would ever be possible. Actually, the reaction forces are like this in this situation: Action Force: Book pulled by Earth Reaction Force: Earth pulled by book Action Force: Book pushes on table Reaction Force: Table pushes on book I got that wrong my first few years teaching Physical Science as well, until I started teaching AP Physics and someone asked a good question. The other examples you put up for Newton's Third are great, though.

+Luc Dunn Glad to see this comment- my thoughts as well! I could also see a beginning physicist thinking that balanced forces can only result in no motion after watching this video as well, while they can actually result in any type of constant motion. Hard to include all the details in a short video I'm sure; otherwise a great video and I appreciate the look at the progression of knowledge through the grades!

[@Retrofire-47]

@@mrs.oneill9852 How would that make sense? if the forces are balanced, surely that would result in stasis? i guess i need to do something studying

[@agogirl88]

I really enjoyed that video! Thank you sir.

WARNING: The example given of Newton's 3rd law (at 3:17) is incorrect.

GOOD JOB

[@jaydenaaron7605]

Thank u sooooooooo much I got an A+ on my test because of you

[@TheZarownyDude]

Great video Mr A!

[@GuerrasLaws]

Physics test: “Without” applying the Energy from within you, choose an object of your choice, and apply only the Force or Net Force needed to push it away from you or pull it towards you. Please let me know if you’re able to. This is only a test. Thank you.

[@FrostKittyPaw]

Eventually you will have videos on everything in science o.o These videos are awesome! Thank you!

[@AAA-uz6bs]

Hi, What program to you use for these presentations? I don't mean the screen recorder, I mean the powerpoint type thing you use. Also, what animation software is that? Is it in the presentation program?

[@samkhang3726]

jamming out to the intro song

[@BlimeyGeezaMate]

YES OMG YOU DO PHYSICS AHHHH IM SO HAPPY

[@AAA-uz6bs]

Thanks a bunch!

[@nida072]

thanks!!!

[@Nepherupito]

Youre doing physics now?

[@purplestarsmile]

Thanks, this helps me alot :)

[@stephenblog98]

Thanks

[@LaurikaPrinsloo]

good luck tomorrow everyone

[@chuy.d4c444]

Hey everyone

[@ItzDjanelle]

yes do more physics videos! i love all your videos. :)

[@arstgkneio]

need more physics! hope to see rotational motion some day!

[@cheng1768]

Yes look

[@kameliecookies]

you push my head

[@toddwolfe7453]

Balanced forces equals 0. 0 eggs will produce 0 chickens. Weight from air pressure plus relative density replace the need for gravity No forces equaling 0 are necessary. Weight from air pressure is the downward force . Just spitballing.

[@cheyennechandler1856]

This was a little confusing

[@as51400]

RAAAAAAAH

[@tahsinrahman1668]

coudnt understand
