Sound Effects
Rolling friction generates sound (vibrational) energy, as mechanical energy is converted to this form of energy due to the friction. One of the most common examples of rolling friction is the movement of motor vehicle tires on a roadway, a process which generates sound as a by-product. The sound generated by automobile and truck tires as they roll (especially noticeable at highway speeds) is mostly due to the percussion of the tire treads, and compression (and subsequent decompression) of air temporarily captured within the treads.

Famous quotes containing the words sound and/or effects:
“It is not only their own need to mother that takes some women by surprise; there is also the shock of discovering the complexity of alternative child-care arrangements that have been made to sound so simple. Those for whom the intended solution is equal parenting have found that some parents are more equal than others.”
—Elaine Heffner (20th century)
“If I had any doubts at all about the justice of my dislike for Shakespeare, that doubt vanished completely. What a crude, immoral, vulgar, and senseless work Hamlet is. The whole thing is based on pagan vengeance; the only aim is to gather together as many effects as possible; there is no rhyme or reason about it.”
—Leo Tolstoy (1828–1910)
