Mechanical energy E of particle, system or object is explained as the sum of kinetic energy K and potential energy U, i.e. E = K + U. It is a scalar quantity having dimensions [ML2T-2] and SI unit joule.
(i) It relays on frame of reference.
(ii) A body may have mechanical energy without having either kinetic energy or potential energy. Though, if both potential and kinetic energies are zero, mechanical energy will be zero. The result may or may not be true, i.e., if E = 0 either both KE and PE are zero or PE negative and KE positive such that KE + PE = 0
Recording of hologram Waves scattered from the object are known as object waves. The coherent waves reaching directly form the source is known as reference waves. When object w
Time dilation (relativity of time) is the proper time interval is dilated when it is measured by an observer with reference to whom it has uniform velocity v This is known as

The impression of sound heard by our ears persist in our mind for 1/10th of a second. If another sound is heard before 1/10 second is over, the impression of the two sound mixes up
In the arrangement shown in figure, an object can be hung from a string (with linear mass density µ = 0.002 00 kg/m) that passes over a light pulley. The string is connected to a v
A thermal imager is used to measure the temperature of a target surface (ε = 1) in the test section of a wind tunnel. The thermal imager must view the target though a window. The t
