Experiment description: Classical simple pendulum with adjustable amplitude and low damping, enabling experiments with duration of app. till 1 hour. The output is in form of the instantaneous angle of deflection (red curve in Figure A 1.2) on time and the counter of number of swings (blue marks). All data are available for downloading.
Description of the use: The remote experiment simple pendulum with multipurpose use, starting from the measurement of acceleration of gravity, kinematics (instantaneous velocity and acceleration with its tangential and normal components), dynamics (acting forces, equation of motion), and energy (potential and kinetic energy, energy conservation law, work of dissipative forces) of curvilinear motion. Experiment is suitable as a demonstration experiment in the lectures, in the seminars as the data source for calculations and in the laboratory exercises.
