Use of video cameras and motion sensor

[ManishAdhikari]

I wanna know how to use video cameras and motion sensor in physics practical

well...if there is any question which involves noticing something which stays there momentarily like ball bouncing to a height or paper cone falling to ground or a ball attached to rubber band rising its max amplitude....for noticing them we use slow motion camera or video and then playback in slow motion
