relation between objects in space

In Mathematics, a well-defined collection of definite objects is called a set. George Cantor is regarded as the "Father of Set theory". The concept of "Sets" is basic in all branches of mathematics. It has proved to be of particular importance in the foundations of relations and..

The term 'degrees of freedom' may be defined in any of the following three ways: The total number of coordinates or independent quantities required to completely specify the position and configuration (arrangement of constituent particles in space) of a dynamic system is the degrees of fr..

Mirror Formula - In a spherical mirror, the distance of the object from its pole is called the object distance (u). the distance of the image from the pole of the mirror is called the image distance (v). You already know that the distance of the principal focus from the pole is ..

According to Newton's law of gravitation, the force of attraction is directly proportional to the mass of the body. Consider two objects of mass m separated by a distance d, then the force between them is given by the relation Two objects of mass m separ..

In real life an object which is moving over a horizontal surface does not continue with constant velocity when the accelerating force is removed. Instead the object slows down and eventually stops. The deceleration is caused by a frictional force between the object and..

Friction as a Contact Force - In real life an object which is moving over a horizontal surface does not continue with constant velocity when the accelerating force is removed. Instead the object slows down and eventually stops. The deceleration is caused by a frictional force be..

Shapes of Molecules - such as linear, triangular, square planar, pyramidal, octahedral etc. The shape of a molecule affects its chemical and physical properties. For instance, some of the unique properties of water are due to the angular shape of its molecule (H 2 O). The stability and the self-rep..

Maximum yield of eggs is obtained by keeping the poultry in comfortable, well ventilated, dry, clean and properly lighted houses. Birds of different ages should be kept separately. The first phase in the life of poultry is called the growing period and the chickens are called growers. During this s..

For both type of lenses, the height of the object is always positive, while the height of the image may be + or - depending upon its nature. As per sign convention for lenses, the height of an inverted and real image is negative and hence the magnification of a lens is negative when ..

According to Newton's law of gravitation, the force of attraction is directly proportional to the mass of the body. Consider two objects of mass m separated by a distance d, then the force between them is given by the relation Two Objects of Mass m Separated by a Dista..
