Consider a system of multiple objects that all interact with each other.  Which of the following statements are true?  (There may be more than one.) Group of answer choicesIf the net external force on the system is zero, then the sum of all linear momentum vectors remains constant.If there are no external forces acting on the system, then the sum of all the linear momentum vectors remains constant.The objects may transfer linear momentum among each other.The objects cannot transfer linear momentum among each other.The linear momentum of each individual object must remain constant.The linear momentum of each individual object can change.

Two bodies A and B having masses in the ratio of 3 : 1 possess the same kinetic energy. The ratio of linear momentum of B to A is :

In a perfectly ELASTIC collision between two perfectly rigid objectsGroup of answer choicesthe kinetic energy of each object is conserved.the kinetic energy of the system is conserved, but the momentum of the system is not conserved.both the momentum and the kinetic energy of the system are conserved.the momentum of each object is conserved.the momentum of the system is conserved but the kinetic energy of the system is not conserved.

The second law of motion states that1 pointto every action there is an equal and opposite reactiona body will continue to be at rest or in motion unless and external force is applied to itif the external force acting on a system of bodies is zero, then the momentum of the system remains constantthe force applied to an object is directly proportional to the mass of the object and the acceleration.
