Acceleration:
It is defined as the rate of change of velocity.
acceleration
Acceleration due to gravity:
acceleration due to gravity
Angular Displacement:
angular displacement
Angular momentum or moment of momentum L:
angular momentum
Angular velocity:
angular velocity
Coefficient of Friction:
coefficient of friction
Coefficient of Thermal conductivity k0:
coefficient of thermal conductivity
Coefficient of viscosity: (η)
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
Heat:
Heat is a form of energy.
Q = [ML2T-2]
Impulse:
impulse
Kinetic Energy (K.E.):
kinetic energy
Latent Heat:
Heat absorbed per unit mass during changed of state.
latent heat
Momentum:
momentum
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
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
Thermal Capacity:
The amount of heat energy required by a body for unit
rise of temperature.
thermal capacity
Velocity:
