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
scales
a photodiode
You can measure speed with items such as a Speed gun, Anemometer (wind), and a Speedometer (used in a car)
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.

No. The instrument used to measure wind speed is an anemometer.
protractor
A thermometer.
scales
Photo sensors and chronometers are used to check for the speed. The vehicle breaks the photo sensor beam, and the chronometers record the speeds.
