How do speedometers work?
A: A speedometer is a gauge that measures the instantaneous speed of a vehicle. Speedometers became standard in all motor vehicles in 1910
Speedometers were created by the Croatian engineer Josip Belušić in 1855
Uses the rotation of the wheels to work
When the cars engine turns over the drive shaft spins to turn the wheels
The speedometer cable which is powered by the driveshaft also spins
A magnet located inside the speed cup (made of aluminum) of the car spins at the same speed as the wheels of the car
This creates eddy currents within the speed cup (localized electrical current induced by a conductor by a varying magnetic field)
Eddy currents cause the speed cup to turn at the same speed in attempt to catch up with the magnet

They make a huge impacts in automobiles and driving but do not take require a lot of materials from the environment.
This is how speedometers have an effect on the environment.
A: Effects on Society
Speedometers are very important in our day to day life and travelling.
Since speedometers indicate how fast you are traveling, they help prevent many accidents from occurring on major roads and highways which can save many lives.
They keep track of your km/h, which makes sure that you are following the rules of the road and helps you control your speed when you reach different areas with different speed limits.
For example on neighbourhood road the limit is 40km/h, 60 km/h on major roads and 80-100km/h on highways. Following the idea of speedometers, you make sure when press your brake pedal according to your speed.
Speedometers help make driving a very efficient and easy way of transportation across the world.
When on a highway or major road, everyone is supposed to follow the speed limit, indicated on the speedometer. When everyone is travelling at the same pace, large amounts of cars can easily flow amongst
