If a pitcher increases her speed from 40mph to 49mph, she has increased the power in her pitch (the energy in the ball) by 50%.

That's only about a 20% increase....22.5 to be exact.

Which one is it..power or energy?

In my pea brain they are the same thing.

Energy = Mass*Velocity^2

40*40= 1600
49*49=2401

50.1% increase

Thanks for the replies and I agree. Also agree she has solid credentials and has done well. The 99.9% tweet just took me back. Took it as there is such a very small percentage of girls who are/were/will be taught correctly and the rest won't or were not. If .1% are doing it or did it right then there apparently aren't many softball pitching coaches around the world that know what they are doing. Of course, she is one of the few that does.............Also, looking at the .1%, if there are 1000 D1 pitchers, only 1 of them is pitching correctly.

Again, that was my take away or what first hit me with the statement. Just seemed to me a bit arrogent and rubbed me wrong.

I am sure she has plenty to offer and will stay tuned and will chalk it up as she was trying to draw attention (bring the viewers in for a closer look at what she has to offer).

You may want to consider editing and rewording your initial post so it doesn’t come across quite as strong. Just a suggestion.

Good suggestion and you are right. Done.

It’s been a while since I took physics, but ... I can Google ...

E= mc^2 with c being the speed of light, not velocity.

Kinetic energy (energy possessed in motion) = 1/2 mv

In terms of physics, power is work/change in time ...

So if we are going to say she is losing half her power ... maybe we need to know what that means ... because it doesn’t mean the same thing in physics. Are you talking the force of the ball? How fast the ball is moving?

In HS, my DD did a drill where she would get open and throw only with her upper body. She would throw around 50MPH. When she went to her full motion, she would throw 60MPH. (The pitching cage was set up so all of her pitches registered on a speed gun.) NOTE: Lower body mechanics are extremely important.

Dr. Holtz She may be a great teacher, but she doesn't know anything about physics.

In physics and engineering, power is the work done divided by the time.

Work is defined as force * distance.

To get a 50% increase in power, the force applied by the pitcher will have to increase by 50%.

Here is a video about pitching mechanics. Note that the wire frame model demonstrates IR.

Yes, hence the wink emojii.. Power is an energy rate.

So because of an exaggeration and a possible loose handle on physics are you all going to miss out of the main and true fact that a majority of pitchers don’t use their lower half properly.

Sorry to say but if your dd is a pitcher she can probably do a better job of generating power with her legs. We all focus on whip, and BI. And as long as the ball is in a good position at 9:00 we are happy, but leg drive is rarely discussed.
