Speed is measured by distance traveled divided by time taken. These radar guns measure exactly how far the ball goes within a time frame.Ê

A Radar gun
Time to cover a measured distance, or a radar gun.
You can detect the speed of a ball by using tools like radar guns, speed cameras, or by calculating the speed based on time and distance measurements. These methods can provide an accurate measurement of the ball's speed at a given moment.
If you put larger diameter tires on your car, the speedometer reading would be slower than the speed measured by a radar gun. This is because larger diameter tires cover more ground per revolution compared to smaller tires, so the speedometer would underreport the actual speed of the vehicle.
The speed of a javelin is typically measured using a radar gun or a high-speed camera. The radar gun calculates the speed of the javelin as it travels through the air, while the high-speed camera captures the motion of the javelin to determine its speed.
== The measurement is made at the point where the ball is when the trigger is squeezed and the contacts close to activate the unit. The gun responds in a "split second" by sending out a pulse, catching the return, and then comparing the two to discover the difference (the Doppler shift). It is so fast that the ball doesn't travel very far in the time it takes the unit to respond and resolve the speed. == It depends upon the radar gun. Some radar guns lock the speed at the instant the operator depresses the trigger. Other radar guns (such as the Bushnell® VelocityTM radar gun) include a feature that locks in the fastest speed that occurred during the entire time the trigger was depressed.
Radar gun.
A radar gun can detect the speed of vehicles of up to 1 mile, on an average. It depends on the radar gun's make and model, it may detect farther than 1 mile.
There are innumerable URLs stating that his ball was measured with a radar gun at that speed in 1974, but I could not find any that explained exactly how accurate the measurement was. There's no question but that Ryan could throw a ball fast, but the question remains on exactly how fast.
A police radar gun measures the speed of a car by sending out radio waves and calculating the speed based on the Doppler effect, which measures the change in frequency of the waves bounced back from the moving car. The radar gun is able to determine the speed at which the car is approaching or moving away from the device.
Could be referring to the time limit (ten seconds) the server has to serve the ball once the whistle has blown. Could also refer to the rule changes that have been implemented to speed up the game, such as scoring on every serve regardless of which team serves.
