Abstract
Described herein are wireless smart devices having integrated force, position, acceleration, and rotational sensing for science education (e.g., Newton'"'"'s laws of motion, kinematics, etc.). An integrated wireless device includes an accelerometer to generate acceleration data based on detecting a current rate of acceleration of the integrated wireless device, a shaft encoder to detect angular positional changes of a shaft or axle of the integrated wireless device over time, and at least one processing unit coupled to the accelerometer. The at least one processing unit is configured to decode angular position data of the shaft encoder into positional data and to synchronize acceleration data received from the accelerometer with the positional data. In one example, a force load cell is coupled to the at least one processing unit. The force load cell measures applied force or impact force.
