I see. What about if a person was parachuting, as they were falling in the air would the position that they are travelling in matter?
As in does the resultant force decrease as a person is hunched/slanted/crouched unlike a vertical position.
Potential synoptic A2 question
I think it would matter as a different angle to the horizontal would reduce, increase or keep the same molecules that are displaced. What exam board are you studying. I'm doing A2 AQA Physics A

I might be a bit retarded here but is the person in some sort of motion that you are taking account of net force?
No not at all it is a good question, I may have negated it, envisualize a person is jumping on the spot. I mean if her acceleration is changing, then F = mg-ma, no?

Oh, in that case the force exerted by the person will be F=ma−mg as the person has overcome his weight but I don't think the net force on the person has changed though, because once the person has jumped he's isolated as if the earth was to be separated from him, if that makes sense. Though I might not have understood the question.

interesting. Thank you, it would only be momentarily, and if something like a human - it would be negligible acting in an insufficinet time

No worries but do research it yourself also as I might not be correct. But yes, it will be the moment when the person exerts the force while he's in contact with the earth.

If the person isn't moving, then the net force is zero. Standing and not moving, net force= zero. Crouching and not moving, net force=zero. Zero=zero, therefore no change in net force.
It is fun. Really like SHM/boyles laws/nuclear physics etc.
WOW I really like SHM and nuclear physics too! My exam board is AQA it's relatively easy but I'm kinda confused on electric fields but cant wait for thermal physics experiments.

By the way what's boyles law?
It overlaps well into M3.
Oh yeah magnetic flux and the like is one of the most difficult topics in physics, I intend to thrush that section out, before finishing.
I've kind of finished everything now apart from magnetic fields/electric fields and parts of medical physics
