  • What is Thermometry?

    Thermometry A branch of science which deals with the measurement of temperature of a substance is known as thermometry. The linear variation in some physical properties of a substance with change of temperature is the basic principle of thermometry and these properties are defined as thermometric property (x) of the substance. Thermometric properties (x) may…

  • What are the different Scales of Temperature?

    Scales of Temperature The centigrade (°C), Farenheite (°F), Kelvin (K), Reaumer (R), Rankine (Ra) are commonly used temperature scales. To construct a scale of temperature, two fixed points are taken. First fixed point is the freezing point (ice point) of water, it is called lower fixed point (LFP). The second fixed point is the boiling…

  • What is Temperature and What are its Dimensions?

    Temperature Temperature is defined as the degree of hotness or coldness of a body. The natural flow of heat is from higher temperature to lower temperature. Two bodies are said to be in thermal equilibrium with each other, when no heat flows from one body to the other. That is when both the bodies are…

  • Motion in One Dimension – Important Points Regarding Acceleration

    Important Points Regarding Acceleration (i)    There is no definite relation between the direction of velocity vector and the direction of acceleration vector i.e. angle between velocity and acceleration  may have any value. For Example (a) In case of projectile motion. (figure) The angle between acceleration and  velocity is at O,  at A and at…

  • Motion in One Dimension – Acceleration

    Acceleration         It is defined as the rate of change of velocity and it is a vector quantity (i)    Instantaneous acceleration : It is defined as the acceleration of a body at some particular instant. Instantaneous acceleration =   = (ii)   Average acceleration :   = = The direction of average acceleration is the direction…

  • Motion in One Dimension – Velocity

    Velocity It is defined as rate of change of displacement and it is a vector quantity (i) Instantaneous Velocity : It is defined as the velocity at some particular instant. Instantaneous velocity is also called simply velocity. Instantaneous velocity = = (ii)Average Velocity : Average velocity = (iii)Uniform Velocity : A particle is said to…

  • Motion in One Dimension – Speed

    Speed  Def : It is the rate of change of distance covered with respect to time covered with the particle and it is a scalar quantity (i)Instantaneous Speed:   It is the speed of a particle at particular instant. When we say “speed”, it usually means instantaneous speed. Instantaneous speed  =   = (ii) Average…

  • Motion in One Dimension – Distance and Displacement

    Distance and Displacement (i) Distance is the length of the actual path travelled by a particle (ii) Displacement of a particle is defined as the change in position vector of the particle (iii) Let us suppose that a particle is moving from the point A to point B through C as shown (a) If we…
