Long metal rail with angled headboard.

Function

Intended for experimental study, physics laboratory work, and conducting physics experiments on: Kinematics. Reference frame, position, motion, and trajectory. What is meant by a moving object. Trajectory and displacement. The difference between displacement and distance traveled. The Cartesian reference system in the plane, orthogonal Cartesian plane. The quadrants. The coordinates of any point on the plane containing the orthogonal Cartesian system. Differences between scalar and vector quantities. Uniform rectilinear motion and its characteristics. How to level the base of a long rail with an incline at the head. What is meant by uniform rectilinear motion. Measuring distances and time. Completing tables and constructing graphs. The slope of the graph and the speed of the moving object. The time function of uniform rectilinear motion. Predicting the future position of a moving object in uniform rectilinear motion. Calculating the speed of the moving object between two positions it occupied, etc. Note: Does not include a manual stopwatch.
