Ballistic apps and potential energy via gravity

[Stubbers]

That’s good. I’m curious what approach you took. Solving for the integral or numerical integration as I would do? And did you use the potential energy conversion to/from kinetic energy?

Gy = GRAVITY * Math.cos(DegtoRad(ShootingAngle + ZeroAngle))
Gx = GRAVITY * Math.sin(DegtoRad(ShootingAngle + ZeroAngle))

Gy = GRAVITY * Math.cos(DegtoRad(ShootingAngle + ZeroAngle))
Gx = GRAVITY * Math.sin(DegtoRad(ShootingAngle + ZeroAngle))

Ok. I think I see where you are going with that.

Ok. I think I see where you are going with that.

vx = velocity on the x-axis
vy = velocity on the y-axis
dv = drag value for the current velocity
dt = time component

dvx = -(vx / v) * dv
dvy = -(vy / v) * dv

vx += dt * dvx + dt * Gx
vy += dt * dvy + dt * Gy
