Equation (7.3) can also be rearranged as
Equation (7.4) states that the linear momentum at time t1 plus the total impulse equals
to the linear momentum at time t2.
7.2.1 The Cotnponents of Linear Itnpulse
If Ʃ fx dt, Ʃ fy dy, Ʃ fz dt are the x, y, and z components of linea’ impulse, we can wdte
Ʃ fx dt = (mv x)2 – ( mv x) 2
Ʃ fy dt = (mv y)2 – ( mv y) 2
Ʃ fz dt = (mv z)2 – ( mv z) 2
The above three scalar equations can be applied independently.
