What is the primary difference between a gyroscope and an accelerometer?

The primary difference is that a gyroscope measures rotational movement. Gyroscopes are devices that detect and measure angular velocity or orientation changes around an axis. This capability allows them to determine how an object is rotating in space, which is essential in various applications, such as navigation systems and stability control.

In contrast, accelerometers primarily measure linear acceleration along one or more axes, providing data on how fast an object is speeding up or slowing down in a straight line. They do not track rotational movement, which is why understanding the function of both devices is crucial. Knowing how each device operates helps in selecting the appropriate tool for different applications in fields such as robotics, aerospace, and sports technology.
