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 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.
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
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!
Friction would be way more of a determining factor than air resistance, assuming they’re traveling along the ground.
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
They have the same momentum (the marble will kill you)
(The bowlingball will also kill you)
What happens if you shoot them against each other with the same momentum?
They shatter. And everyone in the vicinity dies by shrapnel.
Would you rather get hit by bowling ball shrapnel or marble shrapnel?
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.
no I don’t

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.
I choose to imagine they both have equal kinetic energy.
By the blueberry with a surprised look on the left. Aim at my mouth please.
Are the pictures to scale?
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.
