Two discs of moments of inertia I₁ and I₂ about their respective axes (normal to the disc and passing through the centre), and rotating with angular speeds I₁ and I₂ are brought into contact face to face with their axes of rotation coincident. What is the angular speed of the two disc system?

Which of the following doesn’t use the application of Conservation of Angular Momentum?

Space craft orientation is based on the principle of:

What is the relation between torque and angular momentum?

A circus acrobat while performing spins brings his limbs closer to the body. Due to this

An earth satellite is moving around the earth in a circular orbit. In such case, what is conserved?

A child can balance himself on a moving cycle than on a stationary cycle. Based on

A child stands at the centre of a turntable with his two arms outstretched. The turntable is set rotating with an angular speed of 40 rpm. How much is the angular speed of the child if he folds his hands back and thereby reduces his moment if inertia to 2/5 times the initial value? Assume that the turntable rotates without friction.

In system international, angular momentum is measured in
