What was radar mainly used for?
Radar is used in many aspect of our lives from child detection or distance measuring on our cars to image formation in place. Most if not all radar measure range. It was developed by the British (whom still lead the field) in WW2 to locate German planes at night or get early warning of raids.

How do you measure the speed of a hockey puck being shot by a professional?
Using a radar gun similar to one used to measure speed of a baseball being thrown
What is used to measure the speed of a moving body?
A commonly used device to measure the speed of a moving body is a speedometer. It measures the instantaneous speed of a vehicle by calculating the rotational speed of the wheels and converting it into a speed reading. Other methods such as radar guns or GPS devices can also be used to measure speed accurately.
What wave is used in RADAR machines to clock the speed of cars?
RADAR = RAdio Detection And RangingRadio waves in the microwave band are used to measure the speed of cars using a technique called "Doppler RADAR", by measuring the change in frequency of the returned waves.These waves are electromagnetic waves.
What is used for finding the velocity of a moving vehicle?
A "radar gun" is used by police to know the speed of fast moving vehicles. Velocity is a vector. That means it has magnitude and direction. Its magnitude is same as speed.
What equipment is used to measure speed?
Great question. Well, everyday things such as speedometers and stop watches can measure speed. However, if you want to be really accurate then you can use a doppler radar
How is radar used to predict measure weather?
Weather radar devices electronically convert the reflected radio waves into picture that show the location and intensity of precipitation and the speed of the wind.
What is an instrument used for measuring the speed of a motor car?
A RADAR gun is typically used by police to measure the speed of an auto. Using stop watches to measure the elapsed time over a known distance would also give the average speed. A dynamometer can also be used to measure tire rotation in a stationary situation and be converted to an equivalent speed.
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.
