Question

write down the 'principle of conservation of linear momentum'. establish newtons third law from this principle ​

Answer 1

Answer:

***************************************************

Conservation of linear momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.

Answer 2

According to conservation of linear momentum, if there is no net external force acting on the system, the total linear momentum of the system remains conserved. That means For an isolated system the initial linear momentum of the system is equal to the final momentum of the system.

conservation of Linear momentum,

m1u1+m2u2=m1v1+m2v2

m1v1-m1u1=-m2v2-m2u2

$= \: \: \: \: \frac{m1v1 - m1u1}{t} = - \frac{m2v2 - m2u2}{t}$

$= \: \: m1a = - m2a$

$= \: \: \: f1 = \: - f2$
