Summary Comments : [Veritasium] Misconceptions About Falling Objects

Ve********:

Force
F=m*a

Acceleration due to gravity
a=9.8m/s/s

mass of one ball is twice that of another
m1=2Kg
m2=1Kg

F1=19.6N
F2=9.8N

The acceleration due to the Earth's gravity is equal on all falling objects within the gravitational field. The velocity/speed of the object varies depending on aerodynamics and the density of the surrounding material. The force depends upon how massive the object is. Our senses can trick us into thinking that heavy things fall faster because they are more difficult to hold. But the truth is that when you are holding a heavy object, the force due to gravity is still acting upon it. We feel the force of our hands countering the force of gravity. The ball is always accelerating at 9.8m/s/s, from the perspective of the Earth's center. For us to hold the ball in place, we need to exert a force equal in magnitude and negative of the force of gravity. It's easier to understand if you think about it as you playing tug of war with the Earth, except the Earth always wins.

1:47 worlds most over confident person. “I was talking about the weight not the pull”

0:55   ?????

Ha************:

1:55 "the weight is different..." SO CLOSE!

That guy @ 0:57 lol ! Way to live life bro.

Li********:

0:55 I did decent in physics. Speed is constant. I weep for humanity.

Le******:

0:55! The guy in the background!! :D

go**********:

If he asked "total force" it would jog their memories a bit. Also when they said equal force, he should ask: "-so both balls will feel the same if dropped on your stomach?"
Loved the photo-bomb @0:54

Ad********:

''i said the weight is diferent i didnt say the pull is diferent''



pls............ just..... how.... what? its the same thing..........

ji******:

Fg=GMm/r^2

No one in the video took gr11 physics apparently

ya**:

These were the good ol' days, now I see imaginary incomprehensible space time fabric curvatures which the balls follow upon "falling".

Sw*********:

It's disturbing that people think there is a difference between physics and "real life".

D*:

The real point is that the accelerations are identical.
Think that kinda gets lost.

Mi*********:

I wished I was there so I can answer "the force is strong with this one".

I knew the answer was that, in such short distance, the acceleration of the stronger force meets more resistance.  I just wish I was there to answer :P

Jo************:

This was painful to watch. Do people really believe those things?

Cu***********:

"After learning Physics we learned it is actually the same"
Someone's not been paying attention in the classroom.

sa*********:

well he didn't mention air resistance, if he would have been comparing a ball and a piece of paper that would be self explanatory. i guess most people have hard time thinking that a piece of paper and a ball fall at the same rate in in a vacuum.

ji******:

stop confusing force with acceleration. Two objects, same acceleration, the object with higher mass experience greater force.

Pi****:

1:44 hes so damn high xD

Im***********:

The whole time you were asking those college kids the questions i was so dissapointed. None of them even consider the air resistance or anything

Ju****:

lol at the blonde chick who 'did decently in physics'

Li***:

OH MY GOSH I told my science teacher this when he asked a question to the class but he said I was wrong and I have a hard time explaining concepts on the spot so I didn't know how to explain it. Long story short, I ended up looking like an idiot while the teacher explain why I was "wrong". Even though everyone probably forgot about it by now I still can't stop thinking about it.

Do***********:

WOW, that simple explanation at the end clears up everything. This topic confused me for a while. Because F = ma, I thought well, the force must be greater and it is, but more force is required for the same amount of acceleration.

To**********:

Actually, I think they understand physics, the problem is that they mix up terms. Force and Acceleration are different.

al***********:

Does no one remember f=ma??

Lo***:

2:43 like in real life?...

Ty****:

I knew inertia would have something to do with it, inertia is your answer for everything

be*********:

that blonde girl thinks she is smart.....

Ro**********:

''I said the weight is different but the pull is the same'' omfg that girl gave me cancer

Nu***********:

at veryveryveryvery high altitude. the heavier ball will touch the ground first because it has more inertia to overcome air resistance

ba******:

A simple way to understand this is to know that f=ma and that if acceleration(a) is the same for both balls but have different mass (m), then force (f) has to be different.

Ha**********:

Can someone answer my question? If we apply newton's second law mg-R=ma where R is air resistance. So a=g-R/m. And since m is different, a should be different. Isn't it?
Because if we consider a vaccuum, the law will be mg=ma where m is canceled from both sides. That lefts us with a=g=9.81 m/s^2

Ev********************:

"i did decently in physics and i seem to remember that's answer"

Ko***********:

Why are there so many people that don't know why? I'm 11 and i know this. It just shows how sad America is or Australia since he's filming there but my point is WHY ARE AMERICANS SO STUPID!!!???

Em***************:

If the height is great enough (i.e. drop them from a height of 1km), the heavier ball will reach the ground faster.
That's because terminal velocity will be higher for the heavier ball (assuming the balls are identical in every other way, except mass).
In other words, both balls accelerate at the same identical rate. But the heavier one will keep accelerating after the lighter ball already reached its "top speed".
Terminal velocity is reached when the gravitational force equals air resistance. As the video said, the force is greater on the heavy object - greater force will need to be balanced by greater air resistance. Greater air resistance implies greater speed.

Much love <3

Bo******:

Btw I probably knew the actual answer, but while explaining it I would probably have struggled to use the exact terminology while being interviewed by a random guy on a street
For example when they were saying "with the same speed" or something similar, they probably meant that ball 1 and ball 2 had the same velocity of one another, but not that they were constant as he understood.
And also the whole thing is just a misunderstandment between force and acceleration, they were all trying to say that the acceleration was the same, while the weight or gravitational force is bigger in the one with more mass, as we all know that F=ma

Fl*****:

You should've told them about Terminal Velocity, although that might be an overkill for them :D The reason why both balls are hitting ground simultaneously, is because neither of them has time to reach Terminal Velocity. Assuming you drop them from sufficient height (let's say 200th floor), ball with less mass (and less weight force acting on it) will reach terminal velocity faster and stop accelerating, as drag/resistance (aerodynamic drag in this example) force's vector counteracts weight vector and prevents it from further acceleration. The heavier ball continues to accelerate, as drag needs more time to counteract, so it hits ground first. Eventually heavier ball will also reach terminal velocity, but it will be faster.

Interestingly in vacuum, there is no drag and only gravity is affecting them, so both balls will hit ground exactly at the same time, heck even if you put a feather there, it will drop with the same speed :)
