Question

12 of 23
in which type of collision is momentum conserved?
a momentum is never conserved b both elastic and inelastic collisions
c only elastic collisions d only inelastic collisions

Explanation:

In physics, the law of conservation of momentum states that in a closed system, the total momentum before a collision equals the total momentum after the collision, regardless of whether the collision is elastic (where kinetic energy is also conserved) or inelastic (where kinetic energy is not conserved, but momentum still is, as long as no external forces act). So momentum is conserved in both elastic and inelastic collisions.

Answer:

B. Both elastic and inelastic collisions
