For inelastic collsion between two spherical rigid bodies

Options

A. the total kinetic energy is conserved
B. the total mechanical energy is not conserved
C. the linear momentum is not conserved
D. the linear momentum is conserved

Answer

D

Explanation

(d) In an inelastic collision, the particles do not region their shape and size completely after collision. Thus, the kinetic energy of particles no longer remains conserved. However, in the absence of external forces, law of conservation of linear momentum still holds good.
