Thanks for the input. Wishing her a speedy recovery and return to playing. Did her pitch speed coincide with her distance. Curious , her max pitch speed and max long toss, if you don't mind sharing.
She was throwing around 53 in game (drop and fastball) before the break for Covid. After the break 57-58 but not consistent. During the break worked on speed drills like how many pitches in a minute but no long toss, and getting a faster stride off the mound. I had my own injury (subscap tear from arthritis in throwing shoulder) so I wasn't forcing the long toss as I couldn't catch her. Our goal was to pick up 1 MPH per month so she'd be at 60 heading into 14u.Thanks for the input. Wishing her a speedy recovery and return to playing. Did her pitch speed coincide with her distance.

Thank you ... Haley hit 150 ft. Yesterday started at 130 ft. A month ago. Going to clock her speed Friday.
The drag force is proportional to the velocity squared for the velocity range that balls are thrown and acts in the direction that ball is moving. Since the velocity and direction of the ball is constantly changing, and hence the drag force, the deceleration, is in fact, not static.Sure you can. The rate a ball decelerates is static. There are no variables in the equation. Enviromental variables are temperature, altitude, humidity.... A ball at 6000ft alt will fly further than at sea level. Same angle different speeds thrown at the same time will travel known distances
Speed is constant as well. The millisecond the ball leaves the fingertips it starts deceleration and gravity starts pulling it down.
That's like speaking a foreign language right thereThe drag force is proportional to the velocity squared for the velocity range that balls are thrown and acts in the direction that ball is moving. Since the velocity and direction of the ball is constantly changing, and hence the drag force, the deceleration, is in fact, not static.
Edit: If you want to see how distance correlates with initial velocity magnitude, you would need to take the equations of motion with the magnus force and drag force included, and numerically (since the equations are nonlinear) integrate them forward in time (and stop the calculation when the ball reaches the vertical position representing ground). Do this for a range of initial velocities and you would get an idea of how the final (horizontal) distance changes with initial velocity magnitude (assuming the initial velocity direction is constant...)
Way to flex some mental muscles ..... what I’ve noticed in long toss is she is having to get more explosive quicker than currently doing in order to increase distance thrown. Hopefully, she’ll connect the movement to pitching on the rubber. If not, another wasted attempt to improve but not all’s wasted my legs are getting a nice tanThe drag force is proportional to the velocity squared for the velocity range that balls are thrown and acts in the direction that ball is moving.
