Nick is a feckless television salesman who gets fired and impulsively decides that he and his girlfriend, Beth, will move to Butte, MT, which he's read is "the city of the future." "I read that a while ago, so the future should be there by now," he enthuses. He waits until the last moment to tell Carol, his ex and Beth's best friend, about the move. While Nick is working his last day, Sid comes to the couple's house to paint it for the next tenants. He quickly develops an interest in Beth. He, Beth, and Carol get stoned and hang out. When Sid hears about the move, he tells Beth that he's never left Enfield, and has no interest in traveling. Meanwhile, Nick decides to take off on his own. When Beth gets word of this from Carol, she finds solace in Sid's arms. Sid proclaims his love the next morning, and implores Beth to stay. Meanwhile, Nick visits his childhood home, looking for his parents, has an epiphany, and decides to return to Carol. Written by Anonymous
Another example: consider a bowling ball lying on a slippery surface such as ice so that no significant friction is present. Now in your mind try to work out a way that you can apply a force at a single point on the surface of the bowling ball such that it will stay completely still while rotating on the spot. There is no way you can do this! Any point where you push would also make the bowling ball move linearly as well as rotate. To apply a pure rotation you’d have to push on both sides of the ball, canceling the linear component of your force out leaving only torque.
