Entropy, the measure of a system’s thermal energy per unit temperaturethat is unavailable for doing useful work. Because work is obtained from ordered molecular motion, the amount of entropy is also a...
Newton’s first law of motion states that a body continues to be in a state of rest or of uniform motion in a straight line unless it is acted upon by a net external force. Newton’s second...
Frame of reference:When the position of a particle in space changes with time, it is said to be in motion. To describe motion, a frame of reference is needed first and foremost. The set of spatial coordinates...
Electrostatics made of two words Electrostatics= Electro + statics Electro means Electron (charge) statics means in rest position so we can say that Electrostatics is the branch of Physics in which...
