## Can an object have zero momentum but kinetic energy?

No , if a object has zero momentum then it doesn’t have kinetic energy because kinetic energy is half of linear momentum. where KE is kinetic energy and M is mass and V is velocity of the object.

**What does it mean if momentum is zero?**

An object is said to have zero momentum when either the mass or the velocity is zero. Since the mass of the object cannot be zero, the velocity of the object must be zero for momentum to be zero.

### Can a system with net zero momentum have non-zero kinetic energy?

At any time, since the momenta of the two masses are opposite and equal in magnitude, the total momentum of the ‘device’ is zero. However, each possesses kinetic energy, so the total kinetic energy of the system is non-zero.

**Can a system of particles with zero total momentum have non-zero total kinetic energy?**

Two objects of equal mass moving with equal speeds in opposite directions have a total momentum of zero, but their total kinetic energy is definitely nonzero. Basically, the kinetic energy of a system can never be zero as long as there is any kind of motion going on in the system.

## Can a system of particles with zero total momentum have non zero total kinetic energy?

**Which of the following has a momentum of zero *?**

Which of the following has a momentum of zero? mass. If two objects with different masses and traveling with different velocities collide, what law allows you to predict the motion of the objects after the collision?

### Can a system have zero momentum?

Yes, actually a lot of them. The only difficult case is one with a single particle with no internal structure, then you can’t have zero momentum, and have kinetic energy. However, each possesses kinetic energy, so the total kinetic energy of the system is non-zero.

**Can a system have 0 momentum?**

Momenta of 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.
