Videotape the motion of an object
and step
through the
frames to make measurements of position vs time.
NOTES
Use a shutter speed of
1/250 sec for a
clear
image of the ball. Frames are 1/30 sec apart.
To step through the frames, set the
camcorder
to play, then pause, and use the | | > key on the remote to
step.
To transfer images to the computer,
insert the multimedia
card in the camcorder. For each image, pause at the
desired frame and
press the
photo button to transfer the image to the card, then step to
the next frame to
copy. This can also be accomplished by importing the
video into LoggerPro and selecting the frames from within the
program.
