Question

Principle of Impulse and Momentum
Learning Goal
The principle of impulse and momenturn states that the
sum of all impulses created by the external forces and
moments that act on a rigid body during a time interval is
equal to the change in the linear and angular momenta of
the body during that time interval in other words, impulse
is the change in momentum
The greater the impulse exerted on a body, the greater
the body's change in momentum. For example, basebal
Datters swing hard to maximize the impact force and
follow through to maximize the impact time
This principle holds true for both Inear and angular
impulse and momentum
For a rigid-body's planer motion, the equations for the
linear impulse and momentum in the s-y plane are given
by
m(tor) + F, dt = m(voz),
m(t) +EF, dt = m(voy)
Similarly, the equation for the principle of angular impulse
