How It Works

---

   
    Physics has come a long way from the beginning of it's discovery with the help of Sir Isaac Newton.

Because of him we use his laws to use math to explain physical interaction in ordinary life. Below is a few equations needed to explain how painting is accomplished.

Newton's Laws

---

   
#1) An object in motion will stay in motion unless acted on by an eternal force, and an object will stay at rest unless acted on by an external force.
#2) The net Force is equal to it's mass multiplied by it's acceleration.        ( F=ma)
#3) For every action there is an equal but opposite reaction.
      

For painting we will be using all of these rules with a focus of both #2 and #3

 Friction

        These are some more equations that are helpful in understanding the mechanics of painting. 
    For in Static Friction, that is the paint brush against the canvas, the friction caused is "The force of an
object that keeps it from slipping." (Knight,2013)

                           f (static)=$μ$(static)*n 

  This states that μ  is the coefficient  of static friction and that changes for every material, and is multiplied
 by the normal force (n).

$$        Another type of friction is that of Kinetic Friction, which is the friction that is opposing the motion acted
on it.

                           f(kinetic)=$\mathrm{\mu (<i>kinetic)*n\; <br>\; </i>}$

$μ$Which has a coefficient of  friction, just like the static equation.
