We have digital cameras in this generation but in old generation where there was film role, how did the film captured video in motion (not photo) on the top of it how did it record audio? Were these in the same equipment or different audio video equipment?

For film, the audio is recorded separately, and the two combined later. That’s why movies use clapperboards, and why the name, scene and take number are spoken and written on the board. On the film, you can see the information and on the audio you can hear it. The clapping sound made by snapping the clapper board shut lets you syncronise the sound recording to the film.
Film used in movie cameras is essentially the same as film used in still cameras, but in much longer rolls. A movie camera is specially set up to advance the film, expose one frame, then repeat at the required rate (usually 24 frames per second).
