According to newtons second law, force=mass*acceleration. If you could theoretically have a bowling ball fall at a completely constant speed thereby eliminating the acceleration would there be any force when it hit the ground?
>>
>>7792782
no if the ball traverses the ground without slowing down.
yes if it does.

congratualtions, you have discovered neutrinos and dank matter.

if I punch u at a 0acceleration do u get rlly get punched

Yes. Although I'd argue the ball wasn't really "falling" so much as it was traveling toward the ground.

Tie a rope to the bowling ball and lower it at a fixed speed. It will accelerate upwards when it strikes the ground (to a speed of 0, modulo any bouncing). The force of that acceleration will be transferred to the ground.

According to newtons second law, force = dp/dt, so force is the derivative of momentum wrt time, so f=ma if mass is constant

since there is a change in momentum when the ball hits the ground, there is a force that the ground applies to the ball and, 3rd law: the ball applies the same force to the ground
>>
>>7792782
Yes because when the ball hits the ground, its acceleration becomes non zero since the ball stops.
>>
>>7792782
You know there is another equation for collisions that cares not about force but about mass and velocity, right?
>>
>>7793053
it's momentum you motherfucking motherfucker you industrial cock inhaler desu senpai
>>
>>7792782
The ball has to decelerate when it hits the ground you dumpass

unless your ball is somehow going to fall straight through solid dirt
