Baseball Speed Gun
Why does Major League Baseball use a speed gun that measures MPHs for pitchers instead of feet per second?
Feet Per Second seems more logical than Miles Per Hour since a pitcher throws well within a mile!
My guess is to make the number relate-able.
We all know what MPH is... and when you hear 68 miles per hour VS 100 MPH... people inherently relate to those figures.
Feet per second would be too foreign to our minds.
This of course is just a logical conclusion that I have arrived at.

Mitchell Martin 10 yrs old Pitching Bushnell radar gun review 55mph baseball speed
Physics help: Momentum?
Can someone explain these questions to me? ><;
1. How can a huge truck and a small car have the same momentum?
2. Including the ideas of force and time, why does following through with a baseball bat give the ball more momentum and why is it safer for trapeze artists to land in a safety net rather than on the ground?
3. Which requires more impulse, a ball that hits the ground and bounces, or a ball that hits the ground and stays there?
4. Explain why a dart has more speed than the dart gun using the idea of conservation and momentum?
Oh, another question is
what is bouncing and what are examples of change in momentum?
thank you!
1. Momentum is equal to mass times velocity (mv). So even though a truck has a greater mass than a small car, the small car could be traveling at a higher velocity, therefore they could have the same momentum (since it depends on both mass and velocity).
2. If you don't follow through with the bat, then that means you have to stop the bat just as it hits the ball. That means the only momentum the ball will have is its original momentum, but in the opposite direction. If you follow through however, the ball gets the momentum of the bat as well.
For a trapeze artist, the net isn't rigid (and is also much lighter than the ground), so as they fall into it, it will move with them, and therefore take some of their momentum away before they come to a complete stop. If they land on the ground, conservation of momentum says that the ground won't move very much (it has a very high mass) and instead the trapeze artist will have their momentum reflected back upwards as they land (which would hurt a lot).
3. The ball that bounces back requires a higher impulse. The way to think about it is that to stop the ball (i.e. not bounce back) you have to cancel out its original momentum. If you want to bounce it back, you have to cancel out its original momentum, PLUS give it even more momentum (in the other direction) to have it start moving back the way it came.
4. Again, momentum is mass times velocity. The dart has a lower mass than the gun, so after it is fired, they must both have the same momentum in opposite directions (to conserve the 'zero' momentum they had before being fired). If they have the same momentum, the lighter object (the dart) must have a higher velocity to compensate.
EDIT: Bouncing in when the 'direction' of an objects momentum is reversed.
As far as examples of changing momentum, pretty much anytime something speeds up or slows down, there is a change in momentum. Otherwise, if an object loses mass, there is also a change in momentum (if the velocity doesn't change). Lastly, momentum changes when moving objects change direction, even if they stay at the same speed.
