relation between objects in space

Matter and Materials - Matter exists in several phases. If we look at all objects around us, we perceive that some materials have a definite shape and occupy a definite amount of space or volume. We call these materials solids and we can name many objects that are soli..

This is derived from the Greek word 'dynamis', meaning power. Dynamics involves the study of the cause of motion, which is force. When we relate motion of an object to the forces associated with it and to the properties of the moving objects, we are dealing with dynam..

Magnification - Magnification produced by a spherical mirror gives the relative extent to which the image of an object is magnified with respect to the object size. Magnification is expressed as the ratio of the height of the image to the height of the object..

"Remote Sensing" - can be defined as obtaining information about an object by observing it from a distance and without coming to actual contact with it. Infact when we see an object and understand what it is, our eye is sensing that object remotely. This is a broad def..

Wave nature of material objects In 1924, de Broglie's suggested that all material objects including an electron have a dual character; they behave as particles as well as waves. The wavelength associated with a particle of mass 'm', moving with velocity 'v' is given by de Bro..

Motion and Rest - Imagine you are travelling in a moving train. Do you observe any change in your position with respect to your co-passengers? Is there any change of scene you view through the window? The change of scene indicates that the train is moving. That is, an object is said to be..

Rest and motion are relative terms. A person sitting in a moving car is at rest with respect to his or her fellow passengers, but is in motion with respect to other objects or people on the road. Moreover, it is not possible to define 'absolute rest' or 'absolute motion'. ..

Underline each error and write the correction in the space provided. Couples who marries to settle a) __________ down is likely to be headed b) __________ for difficulties, said Dr. Paul, Director of the Institute of Family relations, Los Angeles Most marriage difficulty are ca..

As soon as rockets could break away from the earth's gravity, moon became the next goal. Russians took the lead landing their spacecraft LUNA-3 which photographed the far side of moon in 1959. Meanwhile, the United States launched 11 unmanned moon missions without a single one completing its o..

When an object is kept between two plane mirrors inclined at an angle q , more than one image forms. The total number of images formed in such a case can be related to the angle as follows :..
