Everything you see and do includes Physics, it consistently surrounding us. From the matches, we play to regular development, Physics is experienced every day. In particular, Hammer Throw, an athletic sport, which consists of different fundamental Physics principles. The present men's Hammer Throw world record, set in 1986, is held by Yuriy Sedykh, with a throw of 86.74m. The record is acclaimed to be "incomparable", and there have just been a couple of situations where competitors could toss the hammer near Sedykh's record. Inquiries have emerged whether Sedykh's record will ever be broken. Competitors throw a metal ball (7.26kg for men, 4kg for ladies) for range and distance that is connected to a grip by a steel wire no longer than 1.22m while staying inside a 2.135m distance circle. The distance a competitor can throw the hammer relies upon different and various factors, the most prominent being the release (initial) velocity of circular motion, projectile motion, technique, energy and velocity. With a faster circular and projectile motion with a higher velocity and good techniques, Yuriy’s withstanding world record is breakable.
In 1989, the IAAF (International Athletics Federation) decreased the wire length between the handle and the metal ball to 1.21m. Therefore, it will be significantly more difficult for a thrower to break the record under this rule change. This is due to the constraints of circular motion which is shown in diagram 1 and equation 1.
Circular motion is defined as ‘a movement of an object along the circumference of a circle or rotation along a circular path.’ (Wikipedia). During the procedure of Hammer Throwing, the competitor swings the Hammer in a Circular path, turning the whole body for 3-4 turns, and must apply centripetal force to keep the Hammer in a circular orbit. The Hammer is projected due to the pressure between the Hammer and the Thrower. However, In the case of Hammer Throwing, the acceleration is non-uniform. Not at all like Uniform Circular motion, the Velocity Vector fluctuates during motion movement, instead of uniform circular motion where the Velocity is uniform. The centripetal force can be seen from equation 1, and that a decrease in "r" reduces the Velocity, which results in a shorter range. Subsequently, a higher Velocity can be achieved with a larger radius, which decreases the amount of centripetal force needed to produce a higher velocity. By utlising anatomy.com, it can be seen that Yuriy’s arm span is approximately 80.8cm. If an athlete were to replicate this hammer throw however with a longer arm span such as 83cm, the record could be broken. This can be accomplished by a player with a tall physique, in which the player would have longer arm span.
An athlete that has a taller physique has an advantage in hammer throwing, on the basis of projectile motion. Projectile motion is defined as ‘the motion of an object under the influence of gravity, in a motion of a parabola’ (Wikipedia). In...
