• Waves Wave is a form of disturbance which travels through a material medium due to the repeated f periodic motion of the particles of the medium about their mean positions without any actual transportation of matter. • Characteristics of wave The characteristics of waves are as follows: (i) The particles of the medium traversed […]

• Periodic Motion Motions, processes or phenomena, which repeat themselves at regular intervals, are called periodic. • Oscillatory Motion The motion of a body is said to be oscillatory motion if it moves to and fro about a fixed point after regular intervals of time. The fixed point about which the body oscillates is called […]

• The kinetic theory was developed in the nineteenth century by Maxwell, Boltzman and others. Kinetic theory explains the behaviour of gases based on the idea that the gas consists of rapidly moving atoms or molecules. • Ideal Gas An ideal gas or a perfect gas is that gas which strictly obeys gas laws such […]

• The branch of physics which deals with the study of transformation of heat into other forms of energy and vice-versa is called thermodynamics. Thermodynamics is a macroscopic science. It deals with bulk systems and does not go into the molecular constitution of matter. • A collection of an extremely large number of atoms or […]

• Heat is the form of energy transferred between two (or more) systems or a system and its surroundings by virtue of temperature difference. The SI unit of heat energy transferred is expressed in joule (J). In CGS system, unit of heat is calorie and kilocalorie (kcal). 1 cal = 4.186 J and 1 kcal […]

• Fluids are the sustances which can flow e.g., liquids and gases. It does not possess definite shape. • When an object is submerged in a liquid at rest, the fluid exerts a force on its surface normally. It is called thrust of the liquid. • Pressure The thrust experienced per unit area of the surface […]

• Inter molecular Force In a solid, atoms and molecules are arranged in such a way that each molecule is acted upon by the forces due to the neighbouring molecules. These forces are known as inter molecular forces. • Elasticity The property of the body to regain its original configuration (length, volume or shape) when […]
