PENGEMBANGAN PERANGKAT LABORATORIUM DENGAN APLIKASI INTERFACING SENSOR CAHAYA DENGAN STOPWATCH PADA PERISTIWA GERAK PARABOLA
Abstract: This research has
the objective of knowing the application of light concept as a sensor in the
moment of projectile motion using the aplication of light sensor interfacing in
stopwatch. The making of light sensor device is with electronic circuits
method, while the defeniting the time uses digital stopwatch. Both devices are
combined to be instrument of projectile motion experiment. The result of data
analysis from the graphic, the distance of the time line the curve, that it is
achieved a relationship between the variable and gradient or the degree of the
graphic slope of the line is 4,875. From the calculation the gradient got
gravitational acceleration (g) that is 9,75 m/s2. Gravitational acceleration
that is almost reading the standard
gravitational acceleration, that is 9,8 m/s2 and it has only 0,05 m/s2
in difference from the research. It proves that this device can work well and
stopwatch can automatically work.
