A laser speed gun emits a pulse of light towards a moving vehicle. By measuring the time it takes for the light to hit the vehicle and bounce back, the speed gun can calculate the speed of the car based on the change in distance over time.
One common method to measure the speed of light is using a device called a laser interferometer. This device splits a laser beam into two paths, then recombines them to detect any phase difference caused by the speed of light. Another method involves using a high-speed camera to capture the time it takes for a laser pulse to travel a known distance.
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
The speed of a car is a measure of how fast it is moving over a certain distance in a specific amount of time. It indicates the rate at which the car is changing its position relative to a point of reference.
A laser measure works by emitting a laser beam towards a target and measuring the time it takes for the beam to bounce back. By calculating the speed of light and the time it takes for the beam to return, the device can accurately determine the distance between the device and the target.
You can measure the speed of remote control car using a speedometer,GPS or radar gun. For more information check out traxxas.com/forums/showthread.php?8897772-What-s-the-cheapest-way-to-clock-the-speed-of-an-RC-car
Ask this again but in English please
An anemometer is used to measure wind speed. A Pitot Tube is used to infer speed in an aeroplane,. A speedometer in an ordinary car, and a microwave or laser radar in a Police car.

speed = distance divided by time

The land speed record is typically measured using a combination of GPS technology and laser sensors. GPS provides accurate location data, while laser technology can measure the distance the vehicle travels in a precise manner. By integrating data from both sources, an accurate speed measurement can be obtained.
The speed gun sends a quick series of laser pulses out, pointed at the vehicle you want to check. The pulses reflect back to a receiver. Knowing the speed of light, a computer measures how far away the car is. The distance the car moves between pulses is compared to the time it took to move (all done by a computer chip). Knowing time/distance equals speed.
do you measure how far it will go and then time it
A speed gun is a handheld Radar or Laser unit used by traffic police to check how fast a car is going.
The speedometer in a car does not measure the car's velocity because velocity is an (A) vector quantity and has a direction associated with it (B) vector quantity and does not have a direction associated with it.
Odos measure distance travelled, speedos measure speed at that moment.
speed.. distance..
