A training baseball bat has an internal movable magnet that accelerates to the end of the bat when swung at a fast enough speed. As the magnet moves it passes through a coil that is connected to one or more LEDs so that the LEDs momentarily flash as the magnet moves through the coil. ...
or a tennis ball when both the ball and the player are moving. In golf, the ball sits still and you have plenty of time to get set and make your swing. And, fortunately, the proper way to hit a golf ball
The plate umpire is obligated to uphold the decision of the base umpire to whom he appealed. Important: The defense can only appeal on the checked-swing when the plate umpire calls a ball (indicating no swing and that the ball was not in the strike zone). There is no appeal allowed ...
We also scope out toilet paper situations and warn others that they may need to grab some tissues on the way in. And, perhaps in the biggest display of sisterhood comraderie, when a stall’s lock is broken, we immediately swing our arm up to the top, take hold, and let our partner ...
battery. Lithium metal is not present; instead, positively charged lithium ions travel from the cathode to the anode during charge and from the anode back to the cathode during discharge. This back-and-forth ion flow during the charge and discharge cycles has led to the expressions "swing" an...
Palmer: "I think that's over the line. What goes around, comes around. That's the thing. If guys show you up, sooner or later something is going to happen. It's bad karma. Just play the game respectfully." Blyleven: "If a guy takes a big swing like that, yeah, I would be up...

A stationary magnet can be used to hold the movable magnet until sufficient centrifugal force is imparted by the swing to overcome the magnetic holding force. Spacers can be provided to establish a distance between the magnets as needed to establish a desired swing speed at which centrifugal ...
