The duration of a fall does influence the impact force of an object hitting the ground, as the speed of the falling object increases with time when neglecting air resistance. The impact force is determined by how quickly the object decelerates upon hitting the ground. Assuming a constant stopping time, the force can be calculated using F=ma, where acceleration is derived from speed and stopping time. Therefore, a longer fall duration results in a higher impact force, given the same stopping conditions. This relationship holds true for objects falling near Earth's surface.

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.

Thread 'What is the pressure of trapped air inside this tube?'

As you can see from the picture, i have an uneven U-shaped tube, sealed at the short end. I fill the tube with water and i seal it. So the short side is filled with water and the long side ends up containg water and trapped air. Now the tube is sealed on both sides and i turn it in such a way that the traped air moves at the short side. Are my claims about pressure in senarios A & B correct? What is the pressure for all points in senario C? (My question is basically coming from watching...
