What is the difference between reductionism and unification? |
| Answer» Unification: It is a trial to correlate and unite various universal laws and basic phenomena of nature to explain an activity. For example Maxwell unified electric, magnetic and optical phenomenon on when he explained that light is an electromagnetic wave.Reduction: It is the effort to solve a complex problem by breaking it into simpler parts. It is considered to be heart of physics. For example temperature of a system is reduced to average kinetic. | |

What do you mean by radius of gyration |
| Answer» Radius of gyration or gyradius refers to distribution of the components of an object around an axis. In terms of [mass moment of inertia], it is the perpendicular distance from the axis of rotation to a point mass (of mass, m) that gives an equivalent inertia to the original object(s) (of mass, m).\xa0Mathematically the radius of gyration is the root mean square distance of the object\'s parts from either its center of mass or a given axis, depending on the relevant application. It is actually the perpendicular distance from point mass to the axis of rotation. | |

Define law of conservation of energy and prove it in case of free falling body |
|
Answer» The law states that energy is conserved in a closes system. It can neither be created nor be destroyed but can change its form.In case of free fall potential energy get converted into kinetic energy.Additionally, it is accelerated in ratio 1:3:5:7:9.... According to law of conservation of energy, energy can neither be created nor be destroyed. It can only change its form. |
