Read the passage, decide whether the statements are True (T) or False (F).
A rocket uses fuel to make power for the engine. The fuel is set on fire inside the
rocket. As the fuel burns, it creates gases that have great pressure. These gases are blasted
out of the rocket engines.
These gases all go out the bottom of the rocket engine where it is open. They come
out so fast and with so much power that the rocket is pushed up. It is pushed up so hard
that the rocket overcomes the force of gravity, which tries to keep everything on the
ground. The force that pushes up against the front of the rocket is called thrust.
Unlike an airplane, a rocket does not use wings to help it fly. It just uses the power
and force created by the burning fuel to make enough thrust.
1. A rocket uses the energy from wind to make power for the engine.
2. When the fuel burns, it creates gases that have great pressure.
3. These gases come so fast but they have little power.
4. The rocket is pushed up because it overcomes the force of gravity.
5. The rocket has two wings which help it fly.
