Momentum to Impulse Calculator:
Enter the values of final momentum, Mf(kg.m/s) and initial momentum, Mi(kg.m/s) to determine the value of Impulse, I(N-s).
Momentum to Impulse Formula:
Impulse (I) is the change in momentum of an object when it is subjected to a force over a specific period.
Impulse provides a measure of how much the momentum of an object has changed due to the application of a force.
Impulse is essentially the product of the force applied and the time duration of the force, but it’s often easier to calculate it using the change in momentum.
Momentum itself depends on the object’s mass (m) and its velocity (v). A heavier object or an object moving faster has greater momentum.
An object initially has a certain momentum (Mi) due to its mass and velocity. A force acts on the object for a short duration, causing its momentum to change.
The impulse (I) captures the total effect of this force by considering the difference between the initial momentum (Mi) and the final momentum (Mf) after the force is applied.
Impulse, I(N-s) in Newton seconds is calculated by the difference of initial momentum, Mf(kg.m/s) in kilogram metre per seconds and final momentum, Mi(kg.m/s) in kilogram metre per seconds.
Impulse, I(N-s) = Mi(kg.m/s) – Mf(kg.m/s)
I(N-s) = impulse in Newton seconds, N-s.
Mi(N-s) = initial momentum in kilogram metre per seconds, kg.m/s.
Mf(N-s) = final momentum in kilogram metre per seconds, kg.m/s.
Momentum to Impulse Calculation:
- Finding Impulse (I) Using Initial and Final Momentum:
Given: Mi(kg.m/s) =150kg.m/s, Mf(kg.m/s) = 50kg.m/s.
Impulse, I(N-s) = Mi(kg.m/s) – Mf(kg.m/s)
I(N-s) = 150 – 50
I(N-s) = 100N-s.
- Finding Final Momentum (Mf) Using Initial Momentum and Impulse:
Given: Mi(kg.m/s) = 200kg.m/s, I(N-s) = 75N-s.
Impulse, I(N-s) = Mi(kg.m/s) – Mf(kg.m/s)
Mf(kg.m/s) = Mi(kg.m/s) – I(N-s)
Mf(kg.m/s) = 200 – 75
Mf(kg.m/s) = 125kg.m/s.
