If you are looking for multiple exposures of different locations in one negative the digital method would be compositing separate images as layers in editing software such as PhotoShop or Corel PaintShop. Working with masks it is possible to selectively reveal the layer(s) beneath or use different blending modes to alter how the layer interact with each other. This quickly becomes a very deep subject. To get an idea of what is possible with more advanced skills and techniques check out the work of Renee Robyn.
If you are looking for multiple stop motion shots in one image, such as a falling ball, that would be a studio technique using flash pulses at specified time intervals to record the falling object. Works best in a dark room with no stray light entering it.
