LAW OF INERTIA
[tex]__________________________[/tex]
A spaceship travels far out within a constant speed along a straight line even if no rocket motor propels it along.
↬ In a rocket launch it uses gas to go to space but once it goes to space it doesnt needs a motor to move it just keeps moving because there is no friction and there is less gravity in space it will only stop if there is friction or there is another motion to stop the rocket.
Conclusion:
↬ Force is needed to move or stop and object.
Application Question:
» A spaceship travels far out in space with a constant speed along a straight line even if no rocket motor propels it along:
Because: Rocket lunch is Rocket engines work by action and reaction and push rockets forward simply by releasing their exhaust in the opposite direction at high speed, and therefore can operate in the vacuum of space. In fact, rockets work better in the vacuum of space than in an atmosphere. it will only stop if there is friction or there is another motion to stop the rocket.
Conclusion: It needs more intense force and distance for it to move.
