Question

state the principle of conservation of linear momentum and prove the law is true for collision of two spherical balls moving in a straight line​

Answer 1

Answer:

here is your answer

Explanation:

LINEAR MOMENTUM (p) is the product of mass and velocity

LAW OF CONSERVATION OF LINEAR MOMENTUM

States that if the net force acting on a body is 0 then linear momentum

fnet= change in momentum/time

0= change in momentum/time

since time can not be 0...

this means change in monentum is 0 which is only possible if linear momentums are equal ie linear momentum is constant

now

if two objects are colliding then there net force is not 0

....

but if we consider them as a whole i.e as a single system the net force is 0

there fore law of conservation of linear momentum is always true for collision of two balls
