### When you standing on the floor does the floor exert an upward force against your feet How much force does it exert?

Because your feet are not accelerating, the force exerted by the
floor upon your feet must be exactly the same as the force exerted
by your feet on the floor. If you are standing, the amount of force
exerted by your feet, and thus the amount of force exerted by the
floor, is equivalent to your weight.

###### Asked in Meteorology and Weather, Physics

### How does the amount of pressure you exert on the floor when you are lying down compare with the amount of pressure you exert when you're standing up?

Since your weight remains constant, the only variable is the
area. Pressure is the ratio of Force to Area, implying that the
larger the area the smaller the pressure and vice versa. Since
lying down translate into occupying a larger area than when
standing up, a lower pressure is exerted on the floor while lying
compared to when standing on the floor.

###### Asked in Physics

### If you push a chair across the floor at a constant velocity How is does the force of friction compare with the force you exert?

If you push a chair across the floor at constant velocity, the
force of friction is equal to the force you exert multiplied by
cos(the angle you are pushing at, measured relative to the floor).
This is because if the chair is not accelerating the net force is
0. F=ma, a=0, then F=0. You may hear that the forces are equal but
this is only true if you are pushing parallel to the floor,
straight into the chair.
Suppose you are pushing at an angle of 45 degrees downward,
cos(45)*Fapplied will be forcing the chair downward, increasing the
normal force, but only cos(45)*Fapplied will be negating the
effects of friction.
Therefore the forces are not necessarily equal, the force of
friction is equal to the force exerted multiplied by cos of the
angle the applied force makes with the floor.

###### Asked in Physics

### When standing on the floor does the floor exert an apward force against your fit how much force does exert why you are not move forward by the floor?

Yes, the force exerted by the floor on our feet is equal to the
force that our feet exerted on the floor, or it just depends on
your weight, If you are heavier than the normal. When you stand,
the longer the time you stand, the more pain you feel on your feet.
And we can't be move upward by the force that the floor exerted on
our feet because of the force of our weight that keeps us on the
ground, and also because of gravity.

###### Asked in Home & Garden, Plumbing

### Is there any advantage to installing the water pressure tank on the 2nd floor?

if the well pressure switch goes with the tank then the second
floor pressure would more closely match the well pressure setpoints
and the ground floor would have slightly higher pressure. with the
tank and pressure switch on the lower floor the lower floor would
more closely see the well pressure setpoints and the second floor
would get slightly lower pressure.

###### Asked in High Heels

### Which is more likely to cause damage to a wooden floor a basketball player in athletic shoes or a sports reporter stainding in high heels?

the reporter because there is more pressure being applied to a
smaller floor contact area. the pressure exerted depends on the
area of contact. the smaller the area of contact the greater the
pressure.
for equations use this: Pressure= force/ area
force will usually have a variable of N and area will be a unit
of measurement

### What is an Air Chair?

###### Asked in Physics, Definitions, Waves Vibrations and Oscillations

### What is the definition of sound vibration?

sound vibration is the vibration which is given from a moving
object i.e. a chair moving across the floor, the chair is causing
vibration on the floor, this vibration is carried from the floor
into the air, where then the vibration travels throught the air
until it gets to your ear. this is when the air vibrations hit your
ear drum which then makes you hear the chair scaping across the
floor. hope this helps!!!! :)

###### Asked in Science

### When you are pulling a chair across a room what are you demonstrating?

Depending on your intent you could also be demonstrating:
The grab and release of the frictional forces making a
squeaking noise
The shift in the position of the chair (up on its back legs) as
the forces of gravity and your pulling balance out
The fact the chair only moves when you pull it (Newton's First
Law)
The ease of pulling on a rug and a smooth wood floor
The comparison of the engry required to pull and lift the
chair
