Impulse Calculator:

Enter the values of mass, m_(kg), initial velocity, V_1(m/s) and final velocity, V_2(m/s) to determine the value of Impulse, I_(N.s).

Impulse Formula:

Impulse (I) is a measure of the change in momentum of an object when a force is applied over a period. It quantifies the effect of a force acting on an object and is typically measured in newton-seconds. Impulse is directly related to the change in velocity that an object experiences when subjected to a force.

Mass is the amount of matter in the object, measured in kilograms (kg).

Initial velocity of the object before the force is applied, measured in meters per second (m/s).

Final velocity of the object after the force is applied, measured in meters per second (m/s).

Impulse, I_(N.s) in Newton seconds is calculated by the product of mass, m_(kg) in kilograms and difference of initial velocity, V_1(m/s) in metres per second and final velocity, V_2(m/s) in metres per second.

Impulse, I_(N.s) = m_(kg) * (V_2(m/s) – V_1(m/s) )

I_(N.s) = impulse in Newton seconds, N.s.

m_(kg) = mass in kilograms, kg.

V_1(m/s) = initial velocity in metres per second, m/s.

V_2(m/s) = final velocity in metres per second, m/s.

Impulse Calculation:

1. Finding Impulse (I)

Given:

Mass m_(kg) = 5 kg

Initial Velocity V_1(m/s) = 2 m/s

Final Velocity V_2(m/s) = 8 m/s

Impulse, I_(N.s) = m_(kg) * (V_2(m/s) – V_1(m/s) )

I_(N.s) = 5 * (8 – 2)

I_(N.s) = 5 * 6

I_(N.s) = 30N.s.

2. Determine the Final Velocity (V2)

Given:

Mass m_(kg) = 3 kg

Initial Velocity V_1(m/s) = 4 m/s

Impulse I_(N.s) = 18 N·s

Impulse, I_(N.s) = m_(kg) * (V_2(m/s) – V_1(m/s) )

V_2(m/s) = I_(N.s) /  m_(kg) + V_1(m/s)

V_2(m/s) = 18 / 3 * 4

V_2(m/s) = 6 + 4

V_2(m/s) = 10m/s.
