Is the length of time for which an object is falling directly proportional to the force it hits the ground with?
 
Physics news on Phys.org
The speed of a falling object is proportional to time (assuming no air resistance) V=u+gt

The force it hits the ground with depends on how quickly it stops.
But if we assume the stopping time is the same then F=ma and a (deceleration) is speed/stopping time

So yes.
 
Thanks for the help :)
 
In the context of things falling close to the Earth's surface, yes.
