Cars vibrate.
Heat!
Heat energy from the source causes the particles to oscillate (vibrate) this chains and causes neighbouring particles to vibrate.
Mechanical Waves
Thermal energy causes particles to vibrate. When thermal energy is transferred to an object, its particles gain kinetic energy, causing them to move and vibrate.
"What causes cars to hesitate?
they vibrate..
vibrate or oscillate. This vibration is then transferred through the medium, causing particles in the medium to also vibrate. This transfer of energy produces the mechanical wave.

sound
Sound waves cause the tympanic membrane (eardrum) to vibrate, which in turn causes the malleus (hammer) to vibrate. This vibration is transmitted through the ossicles in the middle ear, ultimately leading to movement of the stapes against the oval window of the cochlea.
