26.
The moment of inertia of a thin rod of mass m and length l,about an axis through its centre of gravity and perpendicular to its length is
27.
When a body of mass m attains a velocity v from rest in time t, then the kinetic energy of translation is
28.
The unit of angular velocity is
29.
If a number of forces are acting at a point, their resultant is given by
(∑V)2 + (∑H)2
(∑V)2 +(∑H)2 +2(∑V)(∑H)
30.
A force acting in the opposite direction to the motion of the body is called force of friction.
