The Four Fundamental Forces Of Physics Explained

Theoretical physics is very complicated, and there is still a lot we don't know about how the universe works. Trace and Julian are here to discuss the four fundamental forces of physics, and why we're still unsure about a lot of things.

"The discovery of a particle about three times as hefty as a proton may lead to insights into the force that holds the nucleus of an atom together."

What are the Fundamental Forces of Physics?
"The fundamental forces (or fundamental interactions) of physics are the ways that individual particles interact with each other."

What are the four fundamental forces of nature?
"As you sit in front of your computer reading this article, you may be unaware of the many forces acting upon you."

Fundamental Forces
"A force which can hold a nucleus together against the enormous forces of repulsion of the protons is strong indeed."

Where Does Gravity Come From?
"Gravity. The average person probably doesn't think about it on a daily basis, but yet gravity affects our every move."

Gravity is the strongest force...           in the morning...

[RhysThePiece]

"Larger the object, the more gravity." You misspoke sir. It should be "More massive the object, the more gravity."

I really like the new guy, he's a good presenter and the right amount of nerdy.

STOP saying physics is hard!! You're speaking to a very large audience, plenty of whom are young and impressionable kids! So if we keep saying physics and math is too hard and if you study it you're not normal, we are likely to shy-away potential future leaders in STEM fields!!

I am no scientist but I've been fascinated by gravity since I had understanding of it and knowing there are still a lot of questions unanswered on the matter can only feed my curiosity. So much to learn and discover. So exciting!

I'd really love to see a video explaining, in detail, much about the fundamental forces and the particles that control/inflence/get influenced by these forces

[GamersDepotGD]

The electromagnetic force is stronger than the weak force, search it up

[carnosinehobs]

Brew simply mentioned Higgs Bosons in a video, and I didn't know what those were, and now I have gone on a very intriguing hunt for answers about basic particle physics on YouTube, leading me here. Thanks.

I thought the 4 Fundamental Forces from strongest to weakest would be the following instead of as stated starting at 1:12…

- Strong Force
- Electromagnetic Force
- Weak Force
- Gravatational Force

[zenzylok]

May the forces of the universe be with you all... Oh wait they already are.

[surendharpillai]

Even though i am a commerce student i love insanely science and to know about science DNews is the best channel probably in youtube.

[YManCyberDude]

The manliness in this video is palpable . . .

[viggovictory]

Well.. The relative strength of the electromagnetic force is 10^36 and relative strength of the weak nuclear force is 10^25. In other words the electromagnetic force is stronger than the weak nuclear force...

[fusebox]

Just to inform people, it is completely not proven that gravitons are the particles, in fact almost disproven because it does not work with the mathematics. One of the main reasons people still theorize about string theory, is that, if the eleven dimensions could work, gravity could be explained, not by a particle, but by a property of all other particles. Gravitons are still just a theory. Although, all of it is just a theory, gravitons are a less likely theory than the other particles.

1:15 CHANGE :- The fundamental forces in descending order of strength are:
Strong nuclear force: The strongest force
Electromagnetic force: The second strongest force
Weak nuclear force: The third strongest force
Gravitational force: The weakest force

Truly. This channel is wonderful. I'm so glad to be a subscriber :)

Force (physics) does not exist physically in the same way that an object with mass, thus making it “not” the initial cause of pushing, pulling, shaping objects, motion, work or being a Vector Quantity (Magnitude + Direction).

In physics, the word, “Force” as we know it, turns out to be nothing more than an expression to express an idea, like one would use the word “Love” to express one's feelings. But, physics and in mathematics, still use “Force” as thou it were something physical that could enable the initial cause of motion making it counterintuitive.

Example: Without applying the Energy from within you, choose an object of your choices to push and pull by simply applying “only” the Force or Net Force.

Meaning that Energy (applied energy) is the origin of motion and not “Force”. Once Energy (E) is applied, it creates what is known as Momentum (p). When this Momentum (object in motion) comes in contact with another object(s), it makes a surface contact that will enable you to push and pull. Example: Ep=ma, Ep=mv and so on. Note: Ep is not to be confused as Kinetic Energy in any way.

Momentum represents things like work, wave, gravity, light, lightning, tsunami, earthquake, current, electricity, motion, magnetism, etc.

Without Energy, there is no Momentum. Without Momentum, there is no surface contact on an object(s) to push, pull, work, shaping objects, motion, etc. Momentum does not and cannot exist without the applied Energy that creates it. Energy and Momentum or “Ep” is the one and only common denominator that links all fundamental forces of nature. Without Ep, all fundamental forces of nature would be inert and non-existence.

Energy is energy, but it’s when Energy (E) is being applied that creates the Momentum (p) making it the initial cause of motion. Example: Ep.

By applying the right amount of Energy, nothing is immovable or unstoppable. ~ Guadalupe Guerra

(2:34) ". . . though, not for long." - Julian suddenly collapses into a heap on the floor and Trace just stares with confusion and awe -

[zmail]

You know I've been driving a Subaru way before it was cool I don't I just ...like how it feels

[sachingiyer]

Trace and Julian make an awesome pair.
