Science > Physics > Oscillations: Simple Harmonic Motion > Theory of Simple Pendulum In this article, we shall study a concept of a simple pendulum, its characteristics. We shall also derive an expression for the period of a simple pendulum. A simple pendulum consists of a point mass suspended from a perfectly rigid support by […]
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 […]

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 > Physics > Atoms, Molecule, and Nuclei > Hydrogen Spectrum The origin of spectral lines in the hydrogen atom (Hydrogen Spectrum) can be explained on the basis of Bohr’s theory. The hydrogen atom is said to be stable when the electron present in it revolves around the nucleus in the first orbit having the […]
Science > Physics > Atoms, Molecule, and Nuclei > Bohr’s Model of an Atom In the last article, we have studied Rutherford’s model of an atom, its merits, and demerits. In this article, we shall study Bohr’s Model of an atom, its merits, and demerits. To overcome the limitations of Rutherford’s model of an atom, […]
Science > Physics > Atoms, Molecule, and Nuclei > Rutherford’s Model of an Atom In this article, we shall study Dalton’s atomic theory, Rutherford’s model of an atom, its merits, and demerits. Dalton’s Atomic Theory: This theory was proposed by English chemist John Dalton in 1808. The main propositions of the theory are as follows: […]
Science > Chemistry > Physical Chemistry > Ionic Equilibria > Solubility Product In this article, we shall study the concept of solubility, solubility product, and its applications. Some ionic solids are highly soluble in water while others are almost insoluble in it. The solubility of ionic solid depends on lattice enthalpy of the salt and […]
Science > Chemistry > Physical Chemistry > Ionic Equilibria > Common Ion Effect In this article, we shall study the common ion effect and its applications. The phenomenon in which the degree of dissociation of any weak electrolyte is suppressed by adding a small amount of strong electrolyte containing a common ion is called a […]
Science > Chemistry > Physical Chemistry > Ionic Equilibria >Buffer Solutions In this article, we shall study the concept of buffer solution, its characteristics, its types, and preparations. Buffer Solution: A solution, which resists the change in its pH value, even on the addition of a small amount of strong acid or base is called […]
