Answer:
is a quantity that describes the effect of a net force acting on an object (a kind of "moving force").
is represented by the symbol J (boldface).
is the product of the average net force acting on an object and its duration.
J = F∆t
is the force-time integral.
J = ⌠
⌡ F dt
is a vector quantity (since force is a vector and time is a scalar).
Impulse-Momentum Theorem
The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it.
J = ∆p
If mass is constant, then…
F∆t = m∆v
If mass is changing, then…
F dt = m dv + v dm
The impulse-momentum theorem is logically equivalent to Newton's second law of motion (the force
