Question

The validity of the conservation of momentum is:​

Answer 1

Answer:

Fnet =0

Explanation:

conservation of momentum is applied only when,

Fnet apply on system=0

so,F=0

delta p/delta t =o

: initial momentum=final momentum

Answer 2

Answer:

During projectile motion and where air resistance is negligible, momentum is conserved in the horizontal direction because horizontal forces are zero. Conservation of momentum applies only when the net external force is zero. The conservation of momentum principle is valid when considering systems of particles.
