I have to write the equation of motion for a projectile thrown vertically, under quadratic air resistance.
The forces acting on the projectile then are, gravity and the quadratic air resistance.
Now, both forces are opposing the projectile, would that mean that if I make gravity negative (-mg) that my air resistance would also need to be negative?
ma = -mg-cv^2 ?
