Definitions
- A device on a watch or chronograph that measures speed based on time and distance. - Used in engineering to measure the rotational speed of a machine or motor. - Refers to a type of surveying instrument used to measure distance and speed.
- A device on a vehicle that measures the speed at which it is traveling. - Used in aviation to measure the speed of an aircraft relative to the air around it. - Refers to a type of instrument used in physics to measure the speed of particles.
List of Similarities
- 1Both devices measure speed.
- 2Both are used to monitor movement.
- 3Both use a scale to display measurements.
- 4Both are commonly found in transportation vehicles.
- 5Both are used in various fields, including engineering and physics.
What is the difference?
- 1Function: Tachymeter measures speed based on time and distance, while speedometer measures speed directly.
- 2Usage: Tachymeter is typically found on watches and chronographs, while speedometer is typically found on vehicles.
- 3Measurement: Tachymeter measures speed over a short distance, while speedometer measures speed over a longer distance.
- 4Scale: Tachymeter uses a logarithmic scale, while speedometer uses a linear scale.
- 5Application: Tachymeter is often used in sports and racing, while speedometer is used for general transportation purposes.
Remember this!
Tachymeter and speedometer are both devices used to measure speed, but they differ in their function, usage, measurement, scale, and application. Tachymeter measures speed based on time and distance and is typically found on watches and chronographs, while speedometer measures speed directly and is typically found on vehicles for general transportation purposes.
