Abstract
Described herein are propulsive force devices for providing propulsive force to integrated wireless devices for science education (e.g., Newton's laws of motion, kinematics, etc.). A propulsive force device includes a motor to drive a rotating member to generate a propulsive force and a motor driver coupled to the motor. The motor driver controls operation of the motor and at least one processing unit is coupled to the motor driver. The at least one processing unit is configured to receive a control signal from an integrated wireless device to adjust at least one parameter of the propulsive force device. When the propulsive force device is mounted to an integrated wireless device, operation of the propulsive force device may be configured to alter, adjust, or otherwise change dynamic properties of the integrated wireless device during science education experiments.
