# The force of wind on baseball

Does anyone know of an equation that I would be able to use for the force of wind acting upon a baseball? I am working on the projectile motion of a baseball with air and wind resistance. I have the equation for the force of air resistance, however, I cannot find the appropriate equation for wind?

Wind is just the movement of air, so the projectile would just see a modified relative air velocity moving by it. Therefore, to account for wind you would just modify the terms in your equations involving air resistance (probably some function of object velocity $$\mathbf f(\mathbf v)$$) to take into account the relative velocity between the air and the object due to the wind. In other words you would replace $$\mathbf f(\mathbf v)$$ with $$\mathbf f(\mathbf v-\mathbf w)$$ where $$\mathbf w$$ is the velocity of the wind.
• $$x(max)=[ [v_{0}^2*sin(2\theta)]/g]- [4v_{0}^3 sin(2\theta)sin(\theta)/3g^2]*\gamma$$ where gamma is the drag coefficient. the first equation represent the x max without air resistance so would I subtract w from v in the second equation? Mar 29 '19 at 13:54
