llongwill ® DISLab Smart Car can accurately obtain real-time parameters of equipment during track operation. With the help of this app, it can achieve real-time collection of physical quantities such as displacement, velocity, acceleration, etc. during the movement of the car, depict corresponding curves, and support further processing such as fitting and differentiation of collected data. Based on llongwill ® DISLab Smart Car supports research on ten specialized experiments, including "measuring displacement and velocity", "measuring acceleration of uniformly variable speed linear motion objects", and "exploring the relationship between acceleration and object force and mass".
