2. Rocket Propulsion So far we have: Impulse = Ft = mv F = Force (N)
t = Elapsed time (s)
m = Mass (kg)
v = Change in velocity (m/s)

3. v = exhaust gas velocity Ft
Rocket Propulsion
So:
F = engine thrust
 t = time to burn fuel
m = mass of fuel burned
v = exhaust gas velocity
Ft =
mv

4. Which Rocket Accelerates faster?B
Demo – F14

6. Rocket Propulsion Thrust of the Engine: F = mv t Big v means big F
Solid Fuel Engine:
Big v means big F
Big v also means lots of pressure
