Ÿ[FONT=&quot] Explain why momentum is conserved in collisions in terms of Newton’s Third Law of motion[/FONT]


No idea why ... my physics teacher never explained ...




Help?


Thanks!

 

[12o9]

Conservation of momentum
Newtons Third Law states that for every action there is an equal and opposite reaction. Therefore when two objects collide, each object exerts an equal and opposite force on each other.



F_1/2 = - F_2/1

F_1/2[FONT=&quot]Δt =[/FONT]- F_2/1[FONT=&quot]Δt[/FONT]
[FONT=&quot]m₂(v[/FONT][FONT=&quot]₂-u[/FONT][FONT=&quot]₂)-m₁(v[/FONT][FONT=&quot]₁-u[/FONT][FONT=&quot]₁[/FONT]

m1u1 + m2u2 = m1v1 + m2v2
