| Abstract: Gravitational acceleration is determined, in practical applications with students using equipment which measures the time of free fall of a ball with an electric timer. The experimental determinations lead to a value of gravitational acceleration g= 9.802 m/s2. Admissible relative error committed by the gravitational acceleration is 4,47*10^-2 % and consequently, the installation meets the following requirements to be used in laboratory work with students.
Knowledge about the electrical devices of students from the Faculty of Electrical is developed by analyzing the electrical schemes of the installation. Knowledge related about the statistical processing of experimental data is developed by calculating the statistical indicators and the task of comparing student’s individual value determined by documentation of its true value as literature. |
