Introduction to an ellipse:
In this section let me call on ellipse formula. An ellipse is the locus of a point which moves so that its distance from a fixed point is in a constant ratio, less than one, to its distance from a fixed line.
The fixed point is called the focus of the ellipse. The fixed line is called the directrix of the ellipse. The constant ratio is called the eccentricity of the ellipse and is denoted by e.
Equation of an Ellipse
Let S(h,k) and ax+by+c=0 be the focus and directrix of an elipse respectively. Let e be the eccentricity of the ellipse.
Let P(x,y) be a general point on the ellipse.This could also help us on types of friction
General form
(a2+b2)[(x-h)2+(y-k)2] = e2(ax+by+c)2
