The energy possessed by a object by virtue of its position or its configuration is called its potential energy.
Concept of potential energy is valid only in conservative field. In conservative force field when a object moves on a round trip then its kinetic energy will not change. But if we assume a point B on the path, then at point B, its kinetic power will not be equivalent as at point A. (Let K.EB < K.EA), we may say that this changes in kinetic energy has stored in configuration of system and this kept energy is known as potential energy of system
is it the current or the voltage which is responsible for electrc shock?
(a) A 400mm length of conductor carrying a current of 25A is situated at right-angles to a magnetic field among two poles of an electric motor. The poles have a circular cross
a column of water contains fine metal particles of radius 2*E(-8) m, which are in thermal equillibrium at 298 K. if there are 1000 particles per unit volume at a given height,how m
When a person stands on a scale in an elevator at rest, the scale reads 800 newtons. When the elevator is allowed to fall freely with acceleration of gravity, the scale reads o
It is the degree to which a object is magnetized when placed in a magnetic field. It can also be described as the pole strength per unit cross sectional area of the object or th
Describe a) Potential difference between two points V, B) Intensity of electric field E. Derive the relation between them.
i want to do experiment online
This is due to the surface tension of water. Because of the surface tension , the drop tends to have minimum possible surface area, and the shape which is possible with minimum su
