Total Impulse Formula
The following formula is used to calculate the Total Impulse.
Itotal = Σ Ft * dt
- Where Itotal is the Total Impulse (N-s)
- Σ Ft is the sum of the thrust forces (N)
- dt is the time (seconds)
How to Calculate Total Impulse?
The following two example problems outline how to calculate the Total Impulse.
Example Problem #1:
- First, determine the sum of the thrust forces (N). In this example, the sum of the thrust forces (N) is given as 250.
- Next, determine the time (seconds). For this problem, the time (seconds) is given as 3.
- Finally, calculate the Total Impulse using the equation above:
Itotal = Σ Ft * dt
Inserting the values from above and solving the equation:
Itotal = 250 * 3 = 750 (N-s)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are provided as the following:
sum of the thrust forces (N) = 150
time (seconds) = 4
Entering these values gives:
Itotal = 150* 4 = 600 (N-s)
