A ROCKET IS A DEVICE THAT SENDS GAS IN ONE DIRECTION TO MOVE IN THE OPPOSITE DIRECTION

WHAT ARE THE PARTS OF A ROCKET?The Nose Cone provides for an aerodynamic design

The payload is the cargo or the crew

The fins stabilize the rocket

HOW DOES A ROCKET WORK?

A rocket burns fuel to make hot gases

A rocket move forward when gases shooting out the back of the rocket push it in the opposite direction (up).

The reaction force that sends a rocket forward is called THRUST

WHAT IS A MULTISTAGE ROCKET?

A multistage rocket is made up of several small rockets stacked on top of each other is called a multistage rocket. Each small rocket is called a stage.

When one stage runs out of fuel, it drops off, and the next stage begins firing.

At the end there is just a single stage left, which is the spacecraft (payload)

THE LATEST ROCKET, SPACEX’S FALCON 9

This is an example of the latest rocket that was launched last week to bring cargo as the payload to the international space station. It is a 2-stage rocket. This was designed with the intent that Stage 1 was recoverable and reusable.
