The earth rotates about an axis passing through its north and south poles with a period of one day. If it is struck by meteorites, then
Relation between torque and angular momentum is similar to the relation between
An earth satellite is moving around the earth in a circular orbit. In such case, what is conserved?
A uniform circular disc of radius 50 cm at rest is free to turn about an axis which is perpendicular to its plane and passes through its centre. It is subjected to a torque which produces a constant angular acceleration of 2.0 rad/sec2. It's net acceleration in m/s2 at the end of 2.0 s is a approximately.
Angular momentum is equal to____.(All the symbols used have their usual meanings)
