Motion-related, information-indicating systems for football generate and present flight relevant information of a thrown football. These systems include a measuring device and an indicating device. In one embodiment, the system measures the spin speed of a football using a gyro. If the spin speed is higher than a preset value, then an LED light on the football is tuned on. A quarterback assesses his spin speed by whether the LED light is on or off. In another embodiment, the indicating device is an LED light positioned on a ring worn by the quarterback. A transmitter/receiver pair transfers signals from the thrown football to the ring. In another embodiment, the system measures the acceleration of a football using an accelerometer. Further the system indicates the acceleration value on an LCD display monitor positioned on the ground. A quarterback checks the LCD display to access the strength of his throw.
