Acceleration:
It is defined as the rate of
change of velocity.

Acceleration due to gravity:
Top
Angular Displacement:
Top
Angular momentum or moment
of momentum L:
Top
Angular velocity:
Top
Coefficient of Friction:
Top
Coefficient of Thermal
conductivity k0:
Top
Coefficient of viscosity: (η)
Top
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.
Top
Gravitational constant:
According to Newton universal law of gravitation.
Top
Heat:
Heat is a form of energy.
Q = [ML2T-2]
Top
Impulse:
Top
Kinetic Energy (K.E.):
Top
Latent Heat:
Heat absorbed per
unit mass during changed of state.
Top
Momentum:
Top
Moment of a force of torque
of moment of a couple:
Top
Moment of Inertia:
Moment of inertia = mass
× (length)2 = [ML2]
I = [ML2]
Top
Planck’s
constant:
Top
Power:
Top
Potential Energy (P.E.):
Top
Pressure:
Top
Specific Heat:
Thermal capacity for unit mass of the body.
Top
Speed
So, dimension of length is +1
and of time is –1 in velocity and speed.
Top
Stress : =
Top
Surface Tension:
Top
Thermal
Capacity:
The amount of heat energy required by a body for
unit rise of temperature.
Top
Velocity:
Top
Work of energy:
Work = force × displacement = F
× s
W =(MLT-2)
× (L) = (ML2T-2)
