A jackhammer is a machine used to break rock. It consists of a chisel that is rhythmically moved upward and downward via an internal motor. "Jackhammer" is also the name of a comic book villain, a wrestling powerslam, a song, a coitus position, and several people (as a nickname).
A jackhammer creates mechanical waves, specifically compression (or longitudinal) waves in the form of vibrations that travel through the surface it is breaking. These waves transmit the force of the jackhammer's impact to the surrounding material, causing it to break apart.
