  Physical quantity and their formula and Dimension   Awaiting Review for Nickels
Tagged with:       [Post New]posted on 29 Aug 2007 14:24:32 IST    
Hi!!!!!!!!  friends. First I would like to thank u all for giving me such tremendous votes.

I have found this article on www.eformulae.com and now pasting it here.


Acceleration:   
 It is defined as the rate of change of velocity.
  acceleration
      Top
 Acceleration due to gravity: 
  acceleration due to gravity
 Top
 Angular Displacement: 
   angular displacement
 Top
 Angular momentum or moment of momentum L: 
   angular momentum
 Top
 Angular velocity: 
   angular velocity   
 Coefficient of Friction: 
   coefficient of friction
 Coefficient of Thermal conductivity k0: 
    coefficient of thermal conductivity
 Top
 Coefficient of viscosity: (?) 
   coefficient of viscosity
 Force:  
   Force =mass ´ acceleration = m ´ a
      F = (M) ´(LT-2) = (MLT-2)
      So, dimension of mass is 1 and that of length is +1and that of time is ?2 in force.
           
 Gravitational constant:  
  According to Newton universal law of gravitation.
 gravitational constant
  Top
 Heat: 
   Heat is a form of energy.  
   Q = [ML2T-2]
 
 Impulse:  
   impulse
    Top
 Kinetic Energy (K.E.): 
kinetic energy
      Top
 Latent Heat:  
    Heat absorbed per unit mass during changed of state.
   latent heat
 Momentum: 
momentum
    Top
 Moment of a force of torque of moment of a couple: 
 moment of a force of torque
 Moment of Inertia:  
   Moment of inertia = mass × (length)2 = [ML2]
    I = [ML2]
 Planck?s constant: 
     planck's constant
 Power:  
power       
 Top
 Potential Energy (P.E.):  
   potential energy
 Pressure: 
      pressure   
 Specific Heat:  
    Thermal capacity for unit mass of the body.
    specific heat
 Speed 
 speed
      
 So, dimension of length is +1 and of time is ?1 in velocity and speed.
 Stress : = 
   stress
 Surface Tension: 
    surface tension
Top      
Thermal Capacity: 
   The amount of heat energy required by a body for unit rise of temperature.
    thermal capacity
    Top
 Velocity:   
     velocity
 Work of energy: 
 Work = force × displacement = F × s
     W =(MLT-2) × (L) = (ML2T-2)
 Young modulus (Y):  
           young modulus   

Hope these will be Useful.

Plz dont forgate to post ur comment.
