The fuel burning in the rockets provides
- a downward thrust
- an upward thrust
- thrust that balances out the force of gravity
- none of the above
The lauch of satellites or rockets is based upon which law?
- Newton's first law of motion
- Newton's second law of motion
- Newton's third law of motion
- None of these
What happens to the rockets moving with high velocity near the Earth's surface?
- They will be burned by the air friction
- They will escape the Earth's gravitational pull
- They will collide with buildings
- They will achieve the corrcet tracjectory
How are the rockets tilted?
- By the structure system
- By the propulsion system
- By the guidance system
- By the payload system
Why are multistage rockets used?
- To spend more money
- They are less expensive
- To give our rocket the desired speed
- To waste the available fuel
