## Is linear momentum conserved in a pendulum?

It is therefore a physical pendulum, and once it begins to swing it has angular momentum. In this pendulum, then, linear momentum is not strictly conserved, but is converted into angular momentum (vide infra).

## Is momentum conserved in a simple pendulum?

Yes. Momentum is always conserved.

**Why is momentum not conserved in a ballistic pendulum?**

The Ballistic Pendulum The bullet colliding with the wood block involves a non-conservative force (the friction that slows the bullet within the block), so the mechanical energy of the bullet + block system is not conserved.

**Why collision momentum is conserved?**

When a collision occurs in an isolated system, the total momentum of the system of objects is conserved. Provided that there are no net external forces acting upon the objects, the momentum of all objects before the collision equals the momentum of all objects after the collision.

### Is linear momentum conserved in a spring?

The total initial momentum of the system is zero. No outside force act on the system in the horizontal direction, so the final horizontal momentum component of the system is also zero. The elastic spring force is conservative. The total energy E = K + U of the system is conserved.

### What is the momentum conservation equation?

The formula for the Law of Conservation of Momentum is p=p’ or m1v1+m2v2=m1v1’+m2v2′. This equation shows us that the sum of the momentum of all the objects in the system is constant.

**What do you mean by law of conservation of momentum?**

conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.

**What is the total momentum before and after collision of colliding pendulum?**

When a collision occurs between two objects, momentum is transferred from one to the other. If no outside forces (such as friction) are present, the total momentum of the objects before the collision is the same as the total after the collision.

#### How do you know if momentum is conserved?

Momentum is conserved when the mass of the system of interest remains constant during the interaction in question and when no net external force acts on the system during the interaction.
