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
As ice floats in water, about 10% of the ice floats above the surface of the water. If we float some ice in a glass of water, what happens to the water level as the ice melts? M
Explain about the monochromaticity of laser. Monochromaticity: The light emitted through a laser is monochromatic, that is this is of one wavelength (colour). Although in ca
A holiday light string of ten bulbs is equipped with shunts that short out the bulbs when the voltage drop increases to line voltage, which happens when a bulb burns out. Every bul
