LINEAR MOMENTUM CONSERVATION

(I) The total linear momentum is conserved only for Elastic collisions not for inelastic. (II) Power is also equal to force xx velocity Which statement is correct ?

Assertion: To conserve linear momentum of a system, no force should act on the system. Reason: If net force on a system is zero, its linear momentum should remain constant.

Principle Of Superposition|Conservation Of Linear Momentum

A planet is revolving around the sun in an elliptcal orbit. Its KE is different for different points and the total energy is negative. Its linear momentum is not conserved the eccentricity decides the shape of the orbit. Linear momentum of the planet is
