I'm trying to figure out the trajectory of a ball but i don't know how to incorporate air friction. I've googled it several times but havn't found anything. Most are just examples but don't describe how to calculate it.
Sh00b said:So...drag equation is:
D = Cd * r * .5 * V^2 * A
With:
Cd = Drag Coefficient
r = air density
V = velocity
A = reference area
To find the drag coefficient, the only thing it describes "The drag coefficient is a number that aerodynamicists use to model all of the complex dependencies of shape, inclination, and flow conditions on aircraft drag."
So I'm now confused on how to get the drag coefficient.
Air friction, also known as air resistance or drag, is calculated using the drag equation: Fd = 1/2 * ρ * v^2 * Cd * A, where Fd is the drag force, ρ is the density of the air, v is the velocity of the object, Cd is the drag coefficient, and A is the cross-sectional area of the object.
Air friction affects the trajectory of a ball by slowing it down and causing it to deviate from its intended path. As the ball moves through the air, it experiences a drag force that acts in the opposite direction of its motion. This force reduces the ball's speed and causes it to follow a curved trajectory instead of a straight line.
To account for air friction, you must include the drag force in the equations of motion for the ball. This can be done by using the drag equation mentioned in the first question. The drag force will act as a resistance force, reducing the acceleration and velocity of the ball as it moves through the air.
The amount of air friction on a ball depends on several factors, including the velocity of the ball, the density of the air, the drag coefficient of the ball, and the cross-sectional area of the ball. Generally, higher velocities, denser air, larger drag coefficients, and larger cross-sectional areas will result in greater air friction on the ball.
No, it is not possible to completely eliminate air friction on a ball. However, you can minimize its effects by reducing the velocity of the ball, choosing a design with a lower drag coefficient, or altering the shape of the ball to decrease its cross-sectional area.
