Document Summary

Ex: hammer thrower, discus: spinning the string & ball, only spins in a circular motion because it is attached to some sort of axis, centripetal force tries to bring the object to the center of rotation. If the force is gone, it will continue along a straight path (when you throw the ball) aka newton"s law. Center seeking: always has an equal and opposite force (centrifugal, has the same magnitude and dimensions but in opposite direction. Centrifugal =trying to break it away from that path. Centrifugal force: tries to break the person through the track onto the other side of it. Centripetal force: tries to draw the bobsled into the center. Eccentric force: a force whose line of action does not pass through the center of gravity of the body on which is acts. An eccentric force tends to cause simultaneously translation and rotation. Couple: an arrangement of two equal and opposite parallel forces.
