The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis

Debate Opening Statement Can we change our impact on the rate of global warming? There are all these campaigns for us to combat global warming and reduce our emissions‚ we have all the science to maybe not stop it but effectively reduce it to stable conditions. It is evident that the temperatures and sea levels are rising and this proves global warming is out there; but it still doesn’t make a difference we still do nothing because Global warming is irreversible; we are so deep

How to Excel in Your Physics Course Most students realize that putting off studying until the day before the exam and then cramming at the last minute is not efficient. Some students do this anyway‚ because so far they have gotten away with it. Perhaps most of the other students you previously competed with had poor study skills. This may have allowed you to adopt poor or non-existent study habits and still keep up‚ or even get good grades if you are naturally a better student. Now that you

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

Vinny Candelora Physics current event 3/3/13 This has never been done before at high energies and represents a significant breakthrough‚ Cline said‚ adding that it also may have implications for fusion as a new energy source. In free space‚ a plane-wave laser is unable to accelerate an electron‚ according to the Lawson-Woodward theorem‚ posited in 1979. However‚ Yu-kun Ho‚ a professor at China’s Fudan University in Shanghai‚ and his research group have proposed a concept of what physicists refer
