Rolling motion on an inclined plane :
velocity v = [2gs] / [ 1+K2 / R2 ].
acceleration a = gsin / [ 1 + K2 / R2 ].
Where, s = distance of inclined plane
K = radius of gyration
R = radius of symmetrical body

In the case of a balanced wheel or torsional pendulum,
T=2 [pie] [ I / C ]. where I = moment of inertia, C=torsional constant=restoring
torque per unit length.

v^2 = u^2 +2as

= v = final velocity

=u = initial velocity

=a = acceleration

=s = displacement
