asked • 03/06/22# Compare momentum of different moving objects

Two objects of the same volume, one is made of steel, the other is made of lead, are moving with the same velocity. Compare their momentum.

The answer: the momentum of the lead object is 1.5 times greater

Hey Gabrielius,

- Recall that momentum = mass * velocity.
- Since they have the same velocity, we're basically asking which object has more mass.
- Look up the densities of each material. The one with the higher density will have the higher mass, since density = mass / volume (and volumes are the same).

Are you asking WHY the lead object has greater momentum? If yes, it is because of density. Momentum is mass times velocity. Density is mass /volume. Since the volumes and velocities are the same, the momentum ratio is determined only by the mass, the ratio of the masses is equal to the ratio of the densities: density lead = 11,343 kg/m^3. density of steel is 7,850 kg/m^3. 11,343/7850 =1.44 ~ 1.503/06/22
