Doppler radar
no you use a stopwatch to measure elapsed time.
It's the gauge in the car/motorbike/whatever that tells you how fast you're going.
An anemometer is used for weather forecasting by meterologists . Aeroplane pilots and sailors need to know the velocity of wind . Therefore they use anemometers to fullfilltis needfor wind speedan anemometer is used to measure wind speedAn Anemometer is a device for measuring wind speed. They are common in Weather Stations.
Well, you probably want to use some sort of device that can measure thousands of feet, as well as something to see how far above sea level it is, so basically then you can use math to figure up the height of the mountain.
The use of a thermometer is to measure hot and cold in Fahrenheit and in Celsius. To measure body temperature, air temperature, atmosphere temperature. It is a scientific instrument to record temperature. It's used to measure temperature of various things. For examples- the human body , weather, liquids etc The word "thermometer" literally means to "measure heat". As such, variations of the device are used to measure the heat of numerous items, including, but not limited to, the body heat of a human or animal, or to ensure proper cooking temperatures, or to trigger a device, such as via an automobile radiator's thermostat, or even to measure the temperature of distant stars.

To take temperature of our body
An amphometer is a device used to measure the passage of a vehicle. It is essentially what police use to track the speed you are going.
A police radar detector is a device used by drivers to detect when law enforcement officers are using radar guns to measure vehicle speed. When a radar gun is detected, the device alerts the driver so they can adjust their speed accordingly to avoid getting a speeding ticket. However, it is important to note that using radar detectors is illegal in some jurisdictions.
One way to measure airspeed is to use a device called a pitot tube.
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.
it can be measured by distance covered and time taken. Speedometer is a device to measure the speed Average Speed = total distance/ total time; speedometers use other correlates to estimate instantaneous speed.
You can use a radar gun or a speed measuring app on a smartphone to measure the speed of the train while standing on the platform. These devices work by emitting signals that bounce off the train and calculate the speed based on the Doppler effect.
You could use a long tape measure or a laser measure device.You could use a long tape measure or a laser measure device.
You could measure the time it takes the toy car to travel a known distance down the ramp. Then, you can calculate the speed by dividing the distance traveled by the time taken. Alternatively, you could use a speed-measuring device such as a radar gun to measure the toy car's speed as it moves down the ramp.
Police use radar technology to measure the speed of a car by sending out a radio wave towards the vehicle. The radio wave bounces off the car and returns to the radar unit. The Doppler effect causes a shift in the frequency of the returning wave, allowing the radar unit to calculate the speed of the car based on this frequency shift.
You use exactly the same instruments to measure speed in the metric system as you use in any other system. For example, a speedometer, or a distance measuring device and a stopwatch. The difference is that these devices are calibrated in metric units, instead of old-fashioned units.
To measure wind speed you use an anemometer. These are sometimes called wind meters. Meteorologists use anemometers to help predict weather.
You can use an anemometer to measure wind strength. An anemometer is a device that detects and measures the speed of the wind. Some common types of anemometers include cup anemometers, vane anemometers, and sonic anemometers.
