The angular movements comprise of athletes, rotating, spinning. swinging, circling, turning, rolling, somersaulting and twisting. It may be athlete or any object that is turning through same angle. In many sports angular motion has great importance. e.g., a gymnast somersault in air, movement of hammer thrower and hammer is also angular, arm rotation at shoulder joint. Linear Movement: Linear motion is described by a straight line movement. It is also known as rectilinear translation. In this the athlete moves in the same direction. e.g., 100 m sprint. In general we can say that all human motions are combination of linear and angular motion, e.g.,a Gymnast balancing on a beam, a cycle racer etc. There is a rotational motion of pedals and wheels along with linear displacement of the cyclist. |
