inertia can be defined as the quantity I= ‚ where M= mass and R= radius of the object. Fortunately for us‚ for the most common objects rotating about typical axes of rotation‚ the summations have already been calculated. For this experiment‚ we used these pre-calculated formulas and values for moment of inertia for theoretical purposes. For objects where the mass is

De’Untre’ Griggs Mr. Hooks 30 September 2014 Physics/4 The Physics Of Dance Essay Physics and dance represent remarkably complementary approaches to human body movement. Those involved with dance and science can easily find the many aspects of science incorporated into the beauty of dance. With its graceful moves‚ jumps‚ turns‚ and kicks‚ dance is a representation of physics at its best and most elegant. Two dance moves in particular come to mind when I think of physics and its effects on dance. They are the grand jeté & projectile motion

Miriam Yanez Physics 018-01 Literature Review 25 April 2012 Biophysics and protein dynamics have shaped our lives when it comes down to advancements in medicine. In living cells‚ proteins are the main components that keep the organism running at its best with every single protein and enzyme having their own function. The discovery of DNA‚ RNA‚ and other protein synthesis became the structures of life in a new perspective in the smallest ways leading to the continuing studies to uncover more

the ball might be going too quick for him to react. The greater the force that is used on the goalie legs to jump‚ the larger the dive to save the ball. The goalie’s reflexes help determine his jump speed to see how quickly he dives for the ball. However‚ the goalie can’t predict or react quickly to every shot. The knuckle shot is highly unpredictable in its movement‚ which leads to a low accuracy rating when used. Goalies are often unable to track and stop an accurate knuckle shot due to its fluctuating

Chapter 19 Nuclear Energy 19.1 Energy in your life Almost everything around us uses electricity and in order to power these devices‚ we must generate it. To create electrical energy‚ we must create thermal energy. Several techniques include using coal‚ natural gas‚ or nuclear thermal to create heat. Once heat is created‚ it is used to vaporize water and use the steam to propel a piston which turns an electric generator. Alternative energy sources include wind‚ solar‚ and micro hydro. 19.2 Nuclear

example of an everyday hero is a firefighter. Firefighters are very courageous‚ they risk their lives every day in order to keep us safe. Another hero is a teacher‚ they come to their job everyday just to insure that we receive an education‚ which shows a sign of loyalty. I would also consider police officers and people who serve in the military to be heroes because they are fearless and stay faithful to their country. I believe that heroes are made‚ not born because you never know what life is going

play and watch soccer games all of the time and yet few people actually realize the physics that are involved in almost everything that they see or do. While there are multiple ways that physics is used in a soccer game‚ this paper explores three parts and the physics that are involved in each one. The three parts that are going to be discussed are passing‚ heading‚ and throw-ins. These three can explain how physics can work from a soccer ball coming or going in each and every direction. Also‚ every
