Question
In a rocket propulsion the rocket launches when hot gases are released. What is the reaction force?
- Rocket launches
- Hot gases are released
- Gravity acts
- Rocket’s timer
Hint:
Rocket launches
The correct answer is: Rocket launches
- In a rocket propulsion the rocket launches when hot gases are released
- The engine produces hot exhaust gases which flow out of the back of the engine.
- In reaction, a thrusting force is produced in the opposite reaction and the rocket launches
- Therefore, the reaction force will be rocket launches.
