Gravitational Acceleration: Determination of “g”
Tempo de Duração: 5:41 minutos
Descrição: To experimentally determine the value of gravitational acceleration using several different methods. Using stroboscopic photography, the first method involves students recording distance and time measurements for a free-falling ball. The other methods require students to make time measurements (use of a stopwatch is required) as a free-fall event is observed in slow motion against a background scale. The varied methods of finding g will allow the student to gain experience in working with the different kinematic equations.
