Question

the principal of conversation of linear momentum is deducted from ​

Answer 1

Answer:According to Newton's third law of motion, the force experienced by A and B are equal and opposite, or, That is, total momentum before collision is equal to total momentum after collision if no external forces act on them which proves the principle of conservation of linear momentum.

Answer 2

Answer:

The force experienced by A and B are equal and opposite, or, That is, total momentum before collision is equal to total momentum after collision if no external forces act on them which proves the principle of conservation of linear momentum.
