Newton's 2nd Law of Motion

Thinking about how force relates to velocity and acceleration

[rhoadess]

One good way to know if one's equation is correct is to use Dimensional analysis, but correct dimensions doesn't guarantee a corresponding relationship with reality. Force=M*L / T^2; |Velocity| = L / T; Acceleration = L / T^2; such that L = length, M = mass, T = time. So F/M = L / T^2 = Acceleration, thus Force divided by mass gives us an acceleration, a change of velocity in time. If you had the ability to change your Higgs particle density you could really change the truck's velocity.

Salman ! your are just "THE BEST" !!

Inertia is resistance to change, it's not equal to mass. For this example it's correct to say that mass is the inertia but think of an ice skater spinning; They can increase their rotational speed by keeping their hands close to their body. The mass is the same as when their hands were far from the body but they speed up because their inertia decreased.

sal, y the product of the 1st equation (velocity) go in the same direction.. tqvm

what Playlist does this video belong to?

[DumbDumbMr]

and sal can a proof video on the area of triangles / quadrilateral ( coordinate geometry ) and some other proofs of statistic formulaes thanks!

[Rimmer]

Are you saying mass and inertia are the same thing?

Hmm, a truck going at 360km/h. That's a FAST truck!

[tahamr]

Ooh man you are accounting the relativistic effects ... i am sorry in this case you are right ... and i am sorry if I offended you .. you should have mentioned brother .. :-)

[jesuistahmid]

it's not a lie, its a very good approximation ;)

[hyperDarklord]

@CodePython @88roro11 @tahamr83
that should be γ^3ma sorry

[roro]

a that point i would have to agree with you :)

[hyperDarklord]

@CodePython @88roro11 @tahamr83
F=dp/dt
P=/ mv
P=γmv
γ=1/sqrt(1-v^2/c^2)
and d/dt(γmv)=γ^ma, F=ma is approximate correct at very low speed, but its not exact, thus a "lie"
I'm sorry if I offended anyone below.
if you don't believe me, ask khan if I'm wrong

[PhrozenTiger]

Holy shit, thats a fast truck .... xD

[PhrozenTiger]

also, I think E = mc^2 is more famous than F = ma ....

[codepython]

could be but if hes not I wanna hear his argument lol

[SebastianEriksson]

Sal apparently uploaded a video about inertia: watch?v=GmHXq4_4JGA

[roro]

i marked them all for spam.. im all for a persons first amendment rights.. but that behaviour is just childish..
