# if all objects in a system have non-zero momentum then the system has a non-zero momentum.

**Can objects in a system have non zero momentum while the total momentum of the system is zero?** – If an object is moving, its momentum cannot be zero. However, this is not necessarily true for a system. Since momentum is a vector, the total momentum of a system can be zero if there are multiple masses.

**Can objects in a system have momentum while the momentum of the system is zero B?** – Can objects in a system have momentum while the momentum of the system is zero? Explain your answer. Yes. Think of the two-car collision example.

**Can a system with net zero kinetic energy have non zero momentum?** – So, the answer is: Yes, an object can have a kinetic energy equal to zero without the momentum being equal to zero.

**What is non zero momentum?** – Momentum is mass times velocity. When an object is moving, it has a non-zero momentum. If an object is standing still, then its momentum is zero. To calculate the momentum of a moving object multiply the mass of the object times its velocity.

**Can a system have momentum but no kinetic energy?** – FALSE – If an object does NOT have momentum, then it definitely does NOT have kinetic energy. However, it could have some potential energy and thus have mechanical energy.

**What is the total momentum of the system after collision if there is no external force acting on the system?** – If there are no external forces acting on this system (consisting of the two masses) the total momentum of the system is conserved.

**What happens to the momentum when all given objects have the same mass but different in velocity?** – Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally.

**Why momentum is considered equal to zero when a body comes to rest?** – The momentum of any object that is at rest is 0. Objects at rest do not have momentum – they do not have any “mass in motion.” Both variables – mass and velocity – are important in comparing the momentum of two objects.

**What is a totally inelastic collision?** – Totally inelastic collision Collision where the objects stick together and have the same final velocity. Also called a perfectly inelastic collision.

**Is it possible to have a situation where momentum is zero but kinetic energy non zero if yes explain with an example if no why?** – Sometimes even if a body has energy, its momentum can be zero. For example: a brick lying on the roof of a building possess potential energy but no velocity so momentum will be zero.

**What is the momentum if kinetic energy is zero?** – If an object’s kinetic energy is zero then its momentum would also be zero. For an object to have no kinetic energy, it must not be moving.

**Does all matter have momentum?** – This is given as a solution to the problem of only massive objects being affected by gravity. However, momentum is the product of mass and velocity, so, by this definition, massless photons cannot have momentum.

**What is the total momentum of a system?** – Definition: The total momentum of a system is the sum of the momenta of each of the objects in the system. Since momentum is a vector, the techniques of vector addition discussed in This chapter must be used to calculate the total momentum of a system.

**What is your momentum if your velocity is zero?** – Because the momenta are “equal but opposite”, the sum of momenta is zero. … An object can have zero momentum when either its mass or its velocity is zero.

**What is an example of a non zero kinetic energy?** – However, each possesses kinetic energy, so the total kinetic energy of the system is non-zero. Another example would be a box filled with gas (air, for instance). The total momentum is zero, since the box isn’t going anywhere as a whole. However, the total kinetic energy of the molecules is not zero.

**When momentum is conserved the total momentum of the system is equal to zero?** – Namely, the total momentum of a system of particles will be conserved whenever the sum of the external forces acting on the system is zero. We will apply this conservation law to collisions of particles and investigate sources of energy loss in these collisions.

**In which type of collision is both the total momentum before and the total momentum after the collision equal to zero?** – Solution: Reasoning: The collision is inelastic, since energy is not conserved. The total momentum of the two pucks is zero before the collision and after the collision.

**At what condition for the total momentum to be conserved in a system?** – The law of conservation of momentum says that the momentum of a closed system is constant in time (conserved). A closed (or isolated) system is defined to be one for which the mass remains constant, and the net external force is zero. The total momentum of a system is conserved only when the system is closed.

**What is the total momentum of the system?** – Definition: The total momentum of a system is the sum of the momenta of each of the objects in the system. Since momentum is a vector, the techniques of vector addition discussed in This chapter must be used to calculate the total momentum of a system.
