How to calculate Force based on pressure?
Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A.Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m 2.In the foot-pound-second (FPS) system, the units are pounds per square inch, or psi.

How to show the difference between force and pressure
- A force can be a push or a pull. When a force is exerted on an object it can change the object's speed, direction of movement or shape.
- Pressure is a measure of how much force is acting upon an area.
- Pressure can be found using the equation pressure = force / area. Therefore, a force acting over a smaller area will create more pressure.

From a technological point of view, pressure mats are able to measure pressure wheter by measuring variation in resistivity of a thin film that puts the sensors in contact with each other (resistive sensors technology) or by sensing the variation in electrical capacity between the surfaces of two films that are able to vary their distance and return to the starting point (capacitive sensors technology).

Force is one of the two most important kinetics quantities and it is "a straight-line push or pull, usually expressed in pounds (lbs) or Newtons (N)" (Knudson, 2007). Force, which is the effect of an interaction between two bodies, it's a vector and it presents a size and a direction.
How do load cells measure force?
Load cells measure force by monitoring variations in the electrical current when a force is being applied over them: the current flows through the sensors, which can be characterised by different types of transducers (strain gauge, piezoelectric and piezoresistive among others), they senses the variation in electrical current and finally this variation is being converted in Newtons (N).

Force plates can measure vertical forces only (in this case they are called single-axis platforms) or both vertical and shear forces (in this case they are called multi-axis platforms). Moreover, they can be unilateral or bilateral, depending if one needs to measure total forces being applied on the plate or forces for each limb separately.
Does pressure change direction?
Pressure is not directed in a specific direction and even by changing the orientation of the surface over which force is acting, this will cause a change in the normal force (the force acting at right angles to the surfaces of objects that are in contact) but not in pressure, which remains the same.
What are the two types of forces that act between two objects?
Forces acting between two bodies can be classified into two broad categories: Contact force and non-contact force. Contact forces are those that act between two objects, which are in direct contact with each other.The two common examples of contact forces are muscular and frictional. I. Frictional Force.
