Eli5 If the equation for force is F=ma why does dropping the same object from 2 different heights change how much an object would be crushed?

In science one year, we did a test of dropping a water bottle from different heights over a Pringle, and we had to protect the Pringle with a paper. But how would increasing the height increase the force is the mass and acceleration is the same?

Force is how hard something is being pulled, not how fast it is moving. Even if gravity were to “stop” midway to the effect that F = ma = m*0 = 0, the object would still be moving and falling. What you have left is momentum i.e., velocity times mass. A faster moving object means more momentum.

Where acceleration is a = F/m = d / t^2, and v = d / t, we can substitute v = a * t = F * t / m.

Velocity is proportional to how much time the force is applied. Momentum is proportional to velocity. The faster the object, the more momentum will need to be transferred. More transferred momentum is like a bigger “hit” to the receiving object.
