Long metal rail with inclined headboard

Função

Intended for experimental study, physics laboratory and carrying out physics experiments on: Kinematics. Reference frame, position, movement and trajectory. What is meant by mobile. Trajectory and displacement. The difference between displacement and distance traveled. The Cartesian reference system on the plane, orthogonal Cartesian plane. The quadrants. The coordinates of any point on the plane that contains the orthogonal Cartesian system. Differences between scalar quantity and vector quantity. Uniform rectilinear movement and its characteristics. How to level the base of the long rail with an inclination at the head. What is meant by uniform rectilinear movement. Measuring distances and time. Completing tables and constructing graphs. The angular coefficient of the graph and the speed of the mobile. The time function of the MRU. Predicting the future position of a mobile moving in MRU. Calculating the speed of the mobile between two positions it has occupied, etc.
