You’ve been hit by, You’ve been struck by, A smooth marble
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.
They have the same momentum (the marble will kill you)
(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?
They shatter. And everyone in the vicinity dies by shrapnel.
Or bounce off of each other, or only one shatters
