Read the following statements carefully and indicate true or false. False If the momentum of a single particle is zero, its kinetic energy may not be zero. False A large force always produces a larger impulse on a body than a smaller force. False The kinetic energy is always conserved both in elastic collisions and inelastic collisions. True The linear momentum of an object is proportional to the mass of the object. True The momentum of an isolated system is always conserved no matter what kind of force is acting inside the system. False If the kinetic energy of a single particle is zero, its momentum must be zero. False If two particles of different masses have equal kinetic energy they also have equal momentum.
