The total weight of the space shuttle decreases in the first 20 seconds due to the rapid combustion of the fuel.
In the first 20 seconds;
- The upward force on the shuttle is 27 million Newtons
- Total weight of shuttle and fuel is 16.5 million Newtons
- The resultant force on the shuttle = (27 - 16.5) million Newtons = 10.5 million Newtons
- The shuttle cannot take off before the first 10 seconds because the weight of the shuttle and fuel is far greater than the upward force on the shuttle.
Why are the hydrogen and oxygen fuels of space shuttles in liquid form?
The fuel used in space shuttles is liquid hydrogen and oxygen.
The fuels are in liquid form in order to slow the combustion rate as well as to reduce the volume occupied by the fuels.
Oxygen is needed in tanks of space shuttles because oxygen is not abundant in space.
The total weight of the space shuttle decreases in the first 20 seconds due to the rapid combustion of the fuel.
In the first 20 seconds;
- The upward force on the shuttle is 27 million Newtons
- Total weight of shuttle and fuel is 16.5 million Newtons
- The resultant force on the shuttle = (27 - 16.5) million Newtons = 10.5 million Newtons
- The shuttle cannot take off before the first 10 seconds because the weight of the shuttle and fuel is far greater than the upward force on the shuttle.
In conclusion, the combustion of the fuel of the shuttle produces the upward force to lift the shuttle.
