Read the passage.
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.
Decide whether the statements are True (T) or False (F).
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 overcome the force of gravity
5. The rocket has two wings which help it fly.
