Physics can be related to sports and fitness on many different levels. When you lift weights‚ play sports or even buy athletic equipment you probably don’t know how much physics was really put into any of it. Weightlifter’s need to know which workout is better. Also the equipment athletes use relate to physics. Manufactures design equipment for athletes‚ which involve physics. The manufactures need to think about what will make the object better and what materials will cause the equipment

Yoyo is a toy that everyone has played at some point in their lives. Yoyo is more than twenty five thousand years old. It is the second oldest toy‚ after dolls. The yoyo was first documented to be invented in Greece with wood‚ metal and terra cotta.2 .The disks were decorated with the pictures of their gods. The yoyo moved to the Orient around 1800. The yoyo was used as a weapon in Philippines. Their version was large with sharp edges and spikes attached to a twenty foot long rope for flinging at

Physics of Sports A sport isn’t just about winning; it is also about strategy‚ how the game is played‚ and performance of the athletes. Physics is the last topic many people associate with sports. However‚ physics can be applied to every aspect of any sport‚ which is a study referred to as Sports Science. Components of this study include gravity‚ projectile motion‚ acceleration‚ force‚ vectors‚ etc. With new technology that physics in sports introduce‚ more possibilities of physical science can

Physics of Volleyball Physics is the study of energy and how it is transferred from one particle to another. There is certainly a lot of energy transferred between objects and players in the sport of volleyball. A few of the concepts of physics that take place during volleyball include gravity‚ displacement‚ velocity‚ acceleration‚ projectile motion‚ and force. These concepts are displayed throughout the different positions on the court. There are three main aspects of volleyball that include

thought of all the physics that is involved in the game of golf? Golf is a game of precision and the smallest miscalculation could mess up a shot. (Real World Physics 2009) The physics of a proper golf swing is more complicated than you might think. You might think that this game is as simple as swinging a club and hitting the ball. But in fact‚ there is a lot more to it. First of all there is the importance of a good technique of coarse‚ but there is also a lot of interesting physics that goes into

Physics of a Guitar (Rough Draft) The guitar is the most played instrument in the music world. The oldest surviving guitar is thought to be made around 1776 in Italy by Gaetano Vinaccia. Though‚ the guitar looks like a simple instrument to construct or play there is a lot of physics behind the creation of it‚ from the strings to the air inside‚ the anatomy‚ and the sound spectrum. There are three types of guitars that are made: nylon acoustic‚ steel-string‚ and electric. Acoustic guitars produce
