its impulse change in momentum
2006-11-09 22:04:55 · answer #1 · answered by gracious_78 3 · 0⤊ 0⤋
There are several terms for the rate of change, impulse being one of them.
Graphically, an impulse change looks like a thin (small time step) square wave. When you hit a pool ball with a cue stick, you impart an impulse of momentum.
A longer (to infinite time) square wave is considered a "constant" rate of change.
Other types:
Ramp, or saw-tooth
Exponential
Sinusoid
many others...

Impulse is change in momentum.Force=change in montum / time.So change in momentum = Force x time = impulse.

You can easily prove that
Impulse=Force*Time (1)
Force=mass*acceleration (2)
and
acceleration=rate of change of velocity with time(3)
combining (2) and (3) we get
Impulse is rate of change of momentum

F = ma = d(mv)/dt (the more general form)
Impulse = â«Fdt = â«d(mv)
Impulse, therefore is change in momentum

impulse = F * dt NOT dF / dt
nai F*dt = m*a*dt = m * du/dt * dt (dt canclels out)
so impulse = m*du/dt
therefore the final product is actually momentum
not rate of change of momentum
chang in momentum strictly.

impulse is change iin momentum
f*t=m*v
