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?

Question

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?

In: 152

Answer 1

Acceleration is a function of time and a higher drop increases the time thus the force unless you have passed the point of terminal velocity.
