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 instrument is use for measuring speed?

Can police radar track vehicles going perpendicular?

Radar or LIDAR (laser measurement of speed) has to be directed toward or away from the path of a moving vehicle, as it measures the speed vector between the measuring device and the vehicle. Traffic radar or LIDAR will not measure the speed of a vehicle moving at a right angle to the direction it is pointed.

How could two observers measure a different speed for the same moving objects?

Two observers could measure a different speed for the same moving object if they are moving at different velocities relative to the object. This is because the speed of an object would appear different depending on the speed and direction of the observer. This effect is known as relative motion.


What is used for checking a motorists speed?

A radar gun is commonly used by law enforcement to check a motorist's speed. This device uses radio waves to measure the speed of a moving vehicle by bouncing the waves off the vehicle and calculating the speed based on the frequency shift.


Which tool is best used to monitor the speed of moving vehicles in a city?

Radar speed guns are commonly used by law enforcement to monitor the speed of moving vehicles in cities. These devices use radio waves to detect the speed of a vehicle by measuring the change in frequency of the waves reflected off the vehicle. Radar speed guns are portable, easy to use, and provide accurate speed measurements.
