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
Infrared Waves: Infrared wave also known as heat wave. These waves are radiation by hot body at dissimilar temperature.

EFFECT OF FIELD ON SUPERCONDUCTIVITY: Critical Magnetic field, H c is the maximum field that can be applied to a superconductor without destroying the superconducting behaviour
A scooterist is racing at a speed of 72 km per hour. If the radius of the wheel is 20 cm, find the angular speed of the wheels. Ans) 72kmph=20m/s 20cm=0.2m; v=rw w=v/r w=20/0

Displacement and Distance A simple animation showing the difference among the distance and the displacement Distance and displacement are two quantities which may seem to mean
Landauer's principle: A principle that states it doesn't take energy to compute data explicitly, but rather it takes energy to erase any data, as erasure is a significant step
