How do spacecraft takeoff?
In the rocket engine large amount of fuel are burnt. The burning fuel expands and is forces itself out the bottom of the rocket. As it pushes down, it pushes the rocket up. If the force pushing the rocket up exceeds its weight, the rocket will take off.
What force sends a rocket to space?
The thrust, which is the force on the rocket due to air. When the fuels are burnt, air (including burnt fuel) is pushed downwards. From Newton's third law, the air exerts an upward force of equal magnitude on the rocket.
What happens when the first stage of the multistage rocket runs out of fuel?
The first stage is jettisoned, to fall back to earth, as the fuel runs out.
What gas is in a rocket?
Rocket fuel.
What fuel is used in rockets?
Rocket fuel.
What will be produced when the rocket fuel is burnt?
Thrust/Speed/Propulsion
What needs to be burnt with oxygen in a rocket motor?
Fuel : for example - kerosene (= jet fuel), alcohol, hydrogen.
What happens to fuel in a car engine?
It is burnt.
What happens when fuel is burnt?

How rocket engines work?
A rocket engine is a reaction engine as the fuel is burnt the thrust created pushes the rocket forward. Newton's 1st law in action; for every reaction there is a equal and opposite reaction.
What happens to the weight of a rocket when it takes off?
The mass of the rocket decreases as fuel burns.
What happens to most of the potential energy from the fuel in internal combustion engines?
un burnt fuel is lost out the tail-pipe.
What happens to coal when it goes to the power staion?
Its burnt into energy. Because coal is a fossil fuel.
What happens when the first stage of the rocket runs out of fuel?
The first stage is jettisoned, to fall back to earth, as the fuel runs out.
Why don't the rockets on a spaceship melt the metal?
Some, or all of the fuel circulates through a cooling jacket around the rocket engine before it is burnt and this cools the rocket's engines. But there might be more to it than that.
