Question

example for linear momentum can't be altered by internal forces​

Answer 1

Answer:

Linear momentum (momentum for brevity) is defined as the product of a system's mass multiplied by its velocity. ... The SI unit for momentum is kg · m/s. Newton's second law of motion in terms of momentum states that the net external force equals the change in momentum of a system divided by the time over which it changes.

Answer 2

Answer:

explosion of bomb is the best example get it as internal forces act but linear momentum remains conserved .
