## Is the momentum of the system of carts conserved?

The momentum of a cart depends on its mass and velocity. The direction of the momentum is the same as the direction of the velocity. During a collision, the total momentum of the system of both carts is conserved because the net force on the system is zero.

### What is the purpose of conservation of momentum lab?

The purpose of this lab is to observe the conservation of momentum for inelastic and elastic collisions. Momentum is inertia in motion, and can be calculated by multiplying an object’s mass by its velocity (i.e., momentum = mass x velocity).

**What is the total momentum of the carts before the collision?**

p1i

The momentum of cart 1 before the collision is p1i. The momentum of cart 1 after the collision is p1f = p1i +Δp1.

**What is the carts change in momentum?**

For carts in an elastic collision, the change in momentum is the mass times the change in velocity. The impulse of a force is the product of the average force and the time interval during which the force acts.

## How do you prove that momentum is conserved?

The law of momentum conservation can be stated as follows. For a collision occurring between object 1 and object 2 in an isolated system, the total momentum of the two objects before the collision is equal to the total momentum of the two objects after the collision.

### What is the combined momentum of the system of two carts before the explosion?

The system consists of the two individual carts initially at rest. The total momentum of the system is zero before the explosion….

Momentum Before Explosion | Momentum After Explosion | |
---|---|---|

Cart & Cannon | (3.5 kg) • (1.27 m/s) = 4.445 kg•m/s | (3.5 kg) • v |

**In what ways does energy and momentum is conserved?**

The laws of conservation of energy and momentum are among the most important and useful principles in physics. Conservation of momentum states that if a system of bodies has no net external forces acting on it, the total momentum is the same at all times (it is conserved).

**What is the relationship between the initial momentum and the final momentum of the cart systems in an elastic collision?**

Inelastic collisions occur when two objects collide and stick together. The initial momentum of one cart plus the initial momentum of the other cart must equal the final momentum of the two cart system once they have collided and stuck together.

## What is the relationship between the total momentum before a collision and the total momentum after the collision?

When two objects collide the total momentum before the collision is equal to the total momentum after the collision (in the absence of external forces). This is the law of conservation of momentum.

### How is momentum conserved in a vehicle collision?

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.

**How do you solve the conservation of momentum?**

Conservation of momentum

- Work out the total momentum before the event (before the collision): p = m × v.
- Work out the total momentum after the event (after the collision):
- Work out the total mass after the event (after the collision):
- Work out the new velocity:
