Why is gravity called a long-range force?
Theoretically it isn't. Gravity is an extremely weak force (consider that a common fridge magnet can overcome the gravitational attraction of the entire Earth) compared to the electromagnetic force (which is the union between the electric and magnetic forces). Why then is gravity dominant at large scales? The reason is that you cannot stop gravity. Gravity only adds to itself. Electromagnetism on the other hand couples to charged particles so you can negate the electromagnetic force by adding opposite charges. So what happens is the following. Imagine you have some powerful positive charge somewhere in the Universe. That charge would very quickly attract negative charges from the area around it. After a while the entire positive charge would be covered by negative charges and the total charge would be zero. Thus the Universe is largely electrically neutral; there are no isolated charges in the Universe. As such there are no charges for the electromagnetic force to act on. This is what practically causes the electromagnetic force to vanish at large scales (this is called charge shielding by the way) whilst the gravitational force does not. So at large scales gravity dominates.
What is the msthematical relationship between force pressure and area?
p= F/A. Or in words, pressure is a force per unit area.
What surrounds electric charges and exerts force on other charges?
An electric field surrounds the charge and exerts force on other charges.
What is the force action on a surface?
Force divided by surface area is called pressure, if that's what you mean.
You are the force of air molecules pushing on an area what are you called?
air
What are relationships between pressure and force and between pressure and area?
pressure is force divided by area
What is the force on a definite area?
The force per unit area is called pressure.

What is the relation between force and preesure?
Pressure = force / area
What is relationship between pressure and force?
Pressure = Force/Area
What is the mathematical relationship between force pressure and are?
Pressure = Force/Area.
The amount of force exerted on a given area is called?
The Amount Of Force
What is defined as force applied over a unit area?
Force per unit area is called "pressure".
What is the relation between pressure and force?
Pressure is defined as force per area
What is inverse square law of magnetism?
The force between two magnetic fields is directly proportional to the product of their magnitudes - and inversely proportional to the square of the distance between them. As an object gets further away, the influencing field decreases because of the increased area it affects. and the equation to find the force that acts between the two magntised objects is Force = (q1 x q2) / r^2 well the force is 'proportional' to that equation but i cant do a symbol for that. the force is measured in Newtons (N) and the r (radius) is measured in metres.
What is the msthematical relationship between force pressure and area?
p= F/A. Or in words, pressure is a force per unit area.
What is the relation between force and area?
Pressure is the force over an area applied to an object in a direction perpendicular to the surface. p = F / A where:p is the pressure,F is the normal force,A is the area.
