/**
* This function lets us simulate a realistic spring-like animation
* when swiping down on the modal.
* There are two forces that we need to use to compute the spring physics:
*
* 1. Stiffness, k: This is a measure of resistance applied a spring.
* 2. Dampening, c: This value has the effect of reducing or preventing oscillation.
*
* Using these two values, we can calculate the Spring Force and the Dampening Force
* to compute the total force applied to a spring.
*
* Spring Force: This force pulls a spring back into its equilibrium position.
* Hooke's Law tells us that that spring force (FS) = kX.
* k is the stiffness of a spring, and X is the displacement of the spring from its
* equilibrium position. In this case, it is the amount by which the free end
* of a spring was displaced (stretched/pushed) from its "relaxed" position.
*
* Dampening Force: This force slows down motion. Without it, a spring would oscillate forever.
* The dampening force, FD, can be found via this formula: FD = -cv
* where c the dampening value and v is velocity.
*
* Therefore, the resulting force that is exerted on the block is:
* F = FS + FD = -kX - cv
*
* Newton's 2nd Law tells us that F = ma:
* ma = -kX - cv.
*
* For Ionic's purposes, we can assume that m = 1:
* a = -kX - cv
*
* Imagine a block attached to the end of a spring. At equilibrium
* the block is at position x = 1.
* Pressing on the block moves it to position x = 0;
* So, to calculate the displacement, we need to take the
* current position and subtract the previous position from it.
* X = x - x0 = 0 - 1 = -1.
*
* For Ionic's purposes, we are only pushing on the spring modal
* so we have a max position of 1.
* As a result, we can expand displacement to this formula:
* X = x - 1
*
* a = -k(x - 1) - cv
*
* We can represent the motion of something as a function of time: f(t) = x.
* The derivative of position gives us the velocity: f'(t)
* The derivative of the velocity gives us the acceleration: f''(t)
*
* We can substitute the formula above with these values:
*
* f"(t) = -k * (f(t) - 1) - c * f'(t)
*
* This is called a differential equation.
*
* We know that at t = 0, we are at x = 0 because the modal does not move: f(0) = 0
* This means our velocity is also zero: f'(0) = 0.
*
* We can cheat a bit and plug the formula into Wolfram Alpha.
* However, we need to pick stiffness and dampening values:
* k = 0.57
* c = 15
*
* I picked these as they are fairly close to native iOS's spring effect
* with the modal.
*
* What we plug in is this: f(0) = 0; f'(0) = 0; f''(t) = -0.57(f(t) - 1) - 15f'(t)
*
* The result is a formula that lets us calculate the acceleration
* for a given time t.
* Note: This is the approximate form of the solution. Wolfram Alpha will
* give you a complex differential equation too.
