CloudLabs Free practice vs Mental Maths Games

In this lab you will find an air rail with two position sensors to measure the start point and end point of movement. For the development of this practice, the student will have the possibility to configure the initial position, the initial velocity and the acceleration. In addition, the simulator allows you to move the sensors along the rail to determine the points where you want to measure the movement, in order to obtain the numerical and graphical results of the movement. It is also possible to visualize the effect of the friction force on the movement by regulating the amount of air that is expelled by the rail.
