    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.

          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.

          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!

              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
