Question

Explain in brief CONSERVATION OF MOMENTUM.

Answer 1

Conservation of momentum is a fundamental law of physics which states that the momentum of a system is constant if there are no external forces acting on the system. It is embodied in Newton's first law (the law of inertia). Suppose we have two interacting particles 1 and 2, possibly of different masses.

Answer 2

Answer:

$\huge{\pink{\green {\sf\boxed{</strong><strong>Definition</strong><strong>⟹</strong><strong>}}}}$

❋ "when two or more bodies interact with each other, their total momentum remains constant or conserved, if no external forces are acting on them."☑️☑️

In other words:

❋ "The total momentum of a system remains constant if no net external unbalanced force acts on it." ☑️☑️

$\Large\boxed{</em></strong><strong><em>Momentum</em></strong><strong><em>\</em></strong><strong><em>:</em></strong><strong><em> </em></strong><strong><em>of</em></strong><strong><em>\</em></strong><strong><em>:</em></strong><strong><em> </em></strong><strong><em>a</em></strong><strong><em>\</em></strong><strong><em>:</em></strong><strong><em> </em></strong><strong><em>body</em></strong><strong><em>\</em></strong><strong><em>:</em></strong><strong><em> </em></strong><strong><em>=\</em></strong><strong><em>:</em></strong><strong><em>Mass</em></strong><strong><em> </em></strong><strong><em>\</em></strong><strong><em>:of</em></strong><strong><em>\</em></strong><strong><em>:</em></strong><strong><em> </em></strong><strong><em>the</em></strong><strong><em> </em></strong><strong><em>\</em></strong><strong><em>:</em></strong><strong><em>body</em></strong><strong><em> </em></strong><strong><em>×</em></strong><strong><em> </em></strong><strong><em>Velocity</em></strong><strong><em> </em></strong><strong><em>\</em></strong><strong><em>:</em></strong><strong><em>of</em></strong><strong><em> </em></strong><strong><em>\</em></strong><strong><em>:</em></strong><strong><em>the</em></strong><strong><em>\</em></strong><strong><em>:</em></strong><strong><em> </em></strong><strong><em>body</em></strong><strong><em>}$

Explanation:

✯This means that whenever a body gains momentum, then some other body in the system must lose an equal amount of momentum, Thus, momentum is neither created nor destroyed.✔️✔️

Momentum of a system, p = constant if net external force acting on it is zero i.e.,F = 0.
