Why is the pressure on the ground more when a man is walking than when he is standing?

WARNING, CALCULUS ALERT!!!
Try this: On a non-digital bathroom scale, stand on it and get your weight. Now stand next to it then jump onto it. It will register a much higher weight. This comes from a rate of change in momentum! Let's math at this a bit: Weight is equal to mass times gravity (W=mg) but weight is a force, so (W=Fweight=mg). So when you stand your total force is just mass times gravity. But when you walk you are generating a downward acceleration when you step, you are 'pushing' down with your leg (this is more obvious when you run). So not only is there a force down from standing but an additional force due to the rate of change of the downward momentum of you leg. So momentum is equal to mass times velocity (p=mv), but your momentum is constantly changing with respect to time so (dp/dt=mdv/dt + vdm/dt, where dv/dt is equal to a). Now since we know your changing momentum is causing a force we may say that F=dp/dt. Now lets put all this back together! Ftotal= Fwieght + Fmomentum then
Ftotal= mg + ma! And that is why walking causes more pressure on the earth than standing.

Why is the pressure on the ground more when a man is walking than when he is standingn?
when a man is standing on ground all his weight is in downward direction and pressure is the force divided by area as force is maximum and area is minimum so pressure will be more when he is standing
When is the pressure on the ground more when a man is lying or when a man is standing?
The person of mass (m) exerts the same force on the ground both standing up and lying down. This can be easily seen through Newtons Second Law ie F = ma. Knowing that pressure is defined as force over area (P = F/Area), it can be seen that the person standing up is applying more pressure to the ground.
Who exerts more pressure on the ground a 500N woman standing in 0.005m high heels or a 500N woman standing in 0.05m work boots?
a women who wears a 500n while standing in 0.5m work boots.
Who exerts more pressure on the ground a 50kg woman standing in high heels or a 50kg woman standing in work boots?
heels bc everything is going into this one little heel but your boots support everything
Who exerts more pressure on the ground -a kg women standing in high heels or a kg women standing in work boots?
High heels. The downward force in both cases is the weight of the woman. However, in high heels, the force acts on a relatively small area whereas with work boots the area is larger. As a result, the pressure is greater with high heels.Estimates suggest that a woman of average average mass, wearing stiletto heels with an area of 1 cm^2, will exert more than 10 times the pressure exerted by a 4 ton elephant standing on one foot.
Why is the pressure on ground more when a men is walking than when a men is standing?
The difference is dynamic pressure vs. static pressure.
Why is the pressure on the ground more when a man is walking than when he is standingn?
when a man is standing on ground all his weight is in downward direction and pressure is the force divided by area as force is maximum and area is minimum so pressure will be more when he is standing
When is the pressure on the ground more-when a man is lying or when a man is standing?
There is more pressure when the man is standing, since pressure is the amount of force acting on a certain area and is calculated by dividing the force by the area. When a man is standing, the area of contact with the ground is less than the area of contact when lying down. Since his weight is constant, there is more pressure when he is standing.
Which produces more pressure on the ground a person standing up or the same person laying down?
standing up, did this on web assign
Who exerts more pressure on the ground a women standing in running shoes a women standing in skis or a women standing in high heel shoes?
assuming they all weigh the same, they would be equal. if not, the heavier one would be exerting more pressure on the ground. if you are looking for an answer relating to pressure exerted in a specific spot, calculate it by surface area.
Why is standing more tiring than walking?
its not

What movements do the leg control?
it controls you in standing,walking and many more
Who exerts more pressure on the ground a 50kg woman standing in high heels or a 50kg woman standing in work boots?
heels bc everything is going into this one little heel but your boots support everything
Can walking in a pool use up more calories than walking on the ground?
yes it does
Which position places more pressure on the spine?
standing
