Conservation of Momentum example 1

The video tutorial explains a collision problem involving two blocks, one smaller and faster than the other, that stick together upon collision. It covers the use of free body diagrams for individual blocks and the system as a whole, highlighting the cancellation of internal forces. The tutorial applies the conservation of momentum to find the final velocity of the blocks and discusses why conservation of energy is not applicable due to nonconservative forces like glue deformation.
