Science > Physics > Work, Power, and Energy > Conservation of Energy In this article, we shall study the concept of energy, types of mechanical energies, and the law of conservation of energy Energy: Different types of energy are mechanical energy, sound energy, heat energy, light energy, chemical energy, electrical energy, atomic energy, nuclear energy. […]
Science > Physics > Oscillations: Simple Harmonic Motion > Composition of Two SHM In this article, we shall study the composition of two SHM. Sometimes particle is acted upon by two or more linear SHMs. In such a case, the resultant motion of the body depends on the periods, paths and the relative phase angles […]
Science > Physics > Oscillations: Simple Harmonic Motion > Numerical Problems on Energy of Particle Performing S.H.M. In this article, we shall study to solve numerical problems to calculate potential energy, kinetic energy, and total energy of particle performing S.H.M. Example – 01: A particle of mass 10 g performs S.H. M. of amplitude 10 […]
Science > Physics > Oscillations: Simple Harmonic Motion > The Energy of Particle Performing S.H.M. In this article, we shall study the concept and expression of the total energy of a particle performing S.H.M. and its constituents. Kintetic Energy of Particle Performing Linear S.H.M.: Consider a particle of mass ‘m’ which is performing linear S.H.M. […]
Science > Chemistry > Chemical Thermodynamics and Energetics > Concept of Internal Energy The internal energy can be defined as the sum of all possible kinds of energies that a system possesses. Every chemical reaction is associated with heat change. Heat is either evolved or absorbed. This is possible only when every substance involved in […]
