If you put larger diameter tires on your car how would the speedometer reading compare to the speed measured by a radar gun?
idon't know about the speedometer reading but the speed the radar gun is the same as the relative movement of the vehicle not the speed at which the tires revolve ...
What instrument is used to measure the speed of a bowling ball?
A radar gun or speed gun is used to clock the speed of a bowling ball. It works by what is called Doppler effect or Doppler shift. See the related links below. ...

How is the speed of a cricket ball during bowling determined?
Current technology allows the use of a "radar gun" to determine the speed of a cricket ball. There is a slight problem in that the ball is frequently thrown "down" ...

A police radar gun measures the speed of a car by?
It measures the time it takes for the radar pulse to go from the radar gun to your vehicle and back. The pulse is fairly constant so the radar gun is getting updates and by comparing the updates to the time it can determine speed. ...

Did nolan Ryan throw abaseball 108mph?
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. ...
When a radar gun says the pitch is 90 miles per hour at what point in the ball's travel to home plate is the radar gun measuring the velocity?
== 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...
What is the fastest ball ever bowled in cricket?
Shoaib Akhtar - 161.3 kph vs England (World Cup 2003) However beware of accepting simple out-of-bowlers-hand radar measured speeds to settle this question. Speeds given for Shoab Akhtar/Brett Lee and others in more modern times are speeds out of the bowlers hand as measured from the batsman's end (by radar gun). One metre after delivery a ball has decreased speed by around 0.97 km/hr. Radar measured speeds are not particularly accurate. This is due to the fact (1) the ball is not travelling...

When was RADAR first used to clock pitching speed?
RADAR was first used to clock pitching speed in 1972. Earl Weaver was the first person to use the RADAR gun to determine speed in baseball. ...

How does a radar gun measure speed?
The principle behind a radar gun is the Doppler Effect; a moving object has shorter wavelengths in front of it than behind it. The formula is: frequency=speed/wavelength A radar gun works by aiming radio waves at a vehicle. The radio waves reflect off of the vehicle and by comparing the frequency of the initial wave with the reflected wave, the speed of the vehicle can be determined. ...

What police is used to catch people speeding?
Police use a radar gun to catch speeders because with a radar gun, you can see the speed limit somebody's doing and if it is way over the real speed limit, you just put on your lights and siren and chase after them. So, you use a radar gun. **********PEACE*********LOVE***************ROCK ON************* ...

What is a radar gun?
A radar gun or speed gun is a device used to measure the speed of different objects. It might by a traffic officer to clock a vehicle's speed. Or perhaps a TV network is using it to clock a baseball pitcher's fast ball. The applications vary, but the unit works by applying the Doppler effect to discover how fast something is going. Basically, the unit sends out a signal and looks at the return signal. It compares the frequency of the...

How can the speed of a distant object in space be measured?
By Radar, the same way a radar gun is used by the police. Bounce a pulse off the object get e measure of the distance. Bounce a second pulse off after a known time interval and get the new distance, then compute speed=(d2-d1)/ interval between pulses. ...

Can a Police Officer use a Radar Gun to clock speed of a car while the Police Officer is driving?

How accurate is a police radar gun when the car is going down hill?
Very accurate, it measures speed and doesn't care if the vehicle is traveling up or down, toward or away from the radar gun. ...
