The video tutorial demonstrates the use of a dynamometer to measure force through the elastic deformation of a spring. It involves an experiment using a wooden block and a sheet of paper to observe the force exerted by the spring and how it overcomes static friction. The tutorial explains the difference between static and dynamic friction and shows how friction decreases when the block moves from the paper to the table surface.
