The bowling ball, because there are 9 other guys with me, we are all dressed in white, and we’re standing in a triangular pattern because we are, in fact, bowling pins.
Depends on the speed. If the bowling ball is moving slower than 10 kph and the marble is moving at ballistic speed of 1000 kph, I would take the bowling ball.
The bowling ball. Cause fuckem that’s why
They have the same momentum (the marble will kill you)
This is what I assumed. Assuming its non-injurious, the marble will sting a lot more, on the other hand, I’d be under a bowling ball (or holding it.)
If its at a significantly injurious amount of momentum, there is no right answer.
(The bowlingball will also kill you)
A bowling ball imparted with the momentum from a slingshot won’t even have the energy to stay air-borne.
The marble imparted with the momentum from a slingshot will fracture or even penetrate your skull.
Momentum is m*v. However, kinetic energy is (1/2)m*v^2, where the velocity is providing exponentially more to the equation.
What happens if you shoot them against each other with the same momentum?
I’m not a Physicist but since they have the same momentum, the marble will have a higher velocity. Let us assume the bowling ball weighs 6000 gm and the marble weighs 20 gm (average weight), the velocity ratio of the marble to bowling ball is 300:1 (300 times faster).
If we assume that both of them are made of the same material, and you throw the bowling ball at 1 m/s, then the marble is launched at nearly Mach 1. I’m pretty sure it will create a neat hole in the bowling ball.
I could be very wrong as well.
They shatter. And everyone in the vicinity dies by shrapnel.
Would you rather get hit by bowling ball shrapnel or marble shrapnel?
How far am I from the collision?
I’ll take a Taco
Let me put this differently:
You’re standing at a lever that can influence the direction of the shrapnel. If you do nothing, 5 people will get hit with bowling ball shrapnel and 1 person with marble shrapnel. If you pull the lever, 5 people will get hit with marble shrapnel and 1 person with bowling ball shrapnel.
What do you do?
Don’t pull lever, save game. Load game, Pull level.
Chaotic evil
What is the velocity of each one?
A slow moving bowling ball causes little to no damage.
A marble fired at around half the speed of light might do some damage.
I choose to imagine they both have equal kinetic energy.
How far are you from the source?
A ways away, I’m not worried about the bowling ball, but that marble will fucking end you.
Whichever is most likely to kill me at its velocity
If they both have the minimum energy to kill you, the marble will probably do it faster.
Are you okay
I mean, you cold just shove the marbles down your throat, but failing that… I know what it’s like to hope that someone pummels you to death with a bowling ball. I hope you don’t genuinely feel that way, but if you do, there are people here - myself included - who would be happy to offer advice to try and not feel that way, or at least provide some temporary relief from that feeling.
And that goes to anyone else reading this who feels that way: no matter where you are in your head, there’s a way out of the darkness. Take it from someone who’s been there ❤️
i legitimately am not in a good emotional/mental place so i do appreciate that
You’ve been hit by, You’ve been struck by, A smooth marble
Marble ball? Just to keep the same syllable count?
I just add an ‘a’ to marble. Marable. It’s a harmless include that has no special ulterior meanings.
Oh, good point. I didn’t think about it that way. Agreed.
glissando on the first syllable of ‘marble’ works great in my head!
Agreed. As another commenter said, “mar-a-bel”. Or at least that’s how I interpreted their response.
If they’re being launched by the same spring mechanism you’re better off with the bowling ball than a little glass bullet.
Depends, how tight is the spring? At high velocity i’d guess a marble will penetrate the body, where at low velocity a marbel would be easier to stop
I think that spring still leaves ambiguity. A very thick, powerful spring like that in an ejection seat could probably get the bowling ball airborne, but wouldn’t actually impart anywhere near the same amount of energy on the marble.
A small elastic band like that used in a slingshot on the other hand would have difficulty getting the bowling ball to fly at all but could turn the marble into a bullet.
And a low velocity marble would translate to a bowling ball bumping into your toe, so I’m not sure what you think the advantage would be there
I think they’ll both be exactly the same difficulty to stop due to conservation of energy. If the spring used is the same for both the bowling ball and the marble, the bowling ball is going to be going much, much slower than the marble.
If we pretend people are homogeneous, both will penetrate through the same amount of “meat”. What means the bowling ball will carve something like a 0.1mm deep 30cm wide hole, while the marble will carve something like a 10cm deep 1cm wide hole.
This feels wrong to my brain. Something that is much heavier must take more energy to move, and therefore to stop. The same velocity doesn’t necessarily imply the same amount of kinetic energy right? Now I gotta go look this up or wait for someone to tell me why I’m stupid
The spring imparts the same amount of energy to the marble and bowling ball. The two objects are not at the same velocity, the marble would be moving significantly faster.
The same velocity doesn’t necessarily imply the same amount of kinetic energy right?
Not at all.
E = 1/2mv^2
Since energy (E) is provided by the same spring in both cases, the energy of the bowling ball and the marble are equal. Since mass (m) is much higher for the bowling ball, the bowling ball’s velocity (v) must be significantly lower.
That’s why I’m stupid! End of shift sleepy brain forgot about the parent comment talking about the spring because of the confusion about velocity. Seems so silly to forget a piece of the conversation while I’m having it, but this happens a lot. I really oughta get an ADHD diagnosis lol
You also have to consider air resistance, that should reduce the energy of the bowling ball when hitting you, making it easier to stop
Friction would be way more of a determining factor than air resistance, assuming they’re traveling along the ground.
Air resistance will affect the marble more since it’s traveling faster. I also feel like either mass (or more likely, density) of the object matters, which would advantage the bowling ball in this aspect too.
Where are the physics nerds at, we need answers!
The bowling ball also has more mass compared to the surface area than the marble because maths, so air resistance would be very little for the bowling ball compared to the marble
no I don’t
By the blueberry with a surprised look on the left. Aim at my mouth please.

its a art
I think you need to see a doctor for that unattached tip
Are the pictures to scale?
Both are moving just under Mach 1
Oh so the real question is: would you rather die by musket or cannon?
Everything is moving at just under Mach 1 if your scale is from zero to lightspeed.
Or if your frame of reference isn’t the same as the object
Then the marble. It would leave a smaller hole.
Is the relative force and distance the same for each? Are they rolled at you?
The bowling ball has more friction so at the same force would be less when it reached you.
The bowling ball has a lower friction to mass ratio and will therefore slow down less
Assuming perfect spheres there is similar or the same friction with the surface it rolls along for both and much larger air resistance for the bowling ball.
Mass doesn’t matter because it is a component of Force which is initially equal for both. The acceleration and speed will be different for both to make forces equal.
The bowling ball will lose more of the force than the marble regardless of which slows down faster.
