State the law of conservation of angular momentum.

Two dics of moments of inertia I_1 and I_2 about their respective axes (normal to the disc and passing through the centre), and rotating with angular speed omega_1 and omega_2 are brought into contact face to face with their axes of rotation coincident. Does the law of conservation of angular momentum apply to the situation? Why?

Derive Kepler's second law of planetary motion,using the law of conservation of angular momentum.

Explain law of conservation of angular momentum.

State the principle of conservation of angular momentum.

State and explain the law of conservation of linear momentum. Explain recoil of a gun and explosion of a bomb.

Derive the law of conservation of linear momentum from Newton's third law of motion.
