a body of mass M is moving with the velocity u when a force is apply on it for time its velocity increases to v right expressions for the following. i initial and final Momentum. ii change in momentum. iii rate of change of momentum also write SI unit of momentum
Answers & Comments
i) Initial momentum (P_initial) = mass (M) * initial velocity (u)
ii) Final momentum (P_final) = mass (M) * final velocity (v)
iii) Change in momentum (ΔP) = Final momentum (P_final) - Initial momentum (P_initial) = M * v - M * u = M * (v - u)
iv) Rate of change of momentum (also known as force, F) = Change in momentum (ΔP) / Time taken (t) = (M * (v - u)) / t
SI unit of momentum: The SI unit of momentum is kilogram-meter per second (kg·m/s). It is denoted as "kg·m/s" or "Ns" (Newton-second), where "N" represents Newton, the unit of force.
