RocketsHow were rockets developed?
How does a rocket work?
What is the main advantage of a multistage rocket?
Chapter 13 Exploring Space
How Do Rockets Work?
A rocket moves forward when gases shooting out the back of the rocket push it in the opposite direction.
Chapter 13 Exploring Space
Rocket Altitude
A rocket’s altitude is how high it is above the ground. Use the graph to answer the following questions about how a model rocket’s altitude changes over time.
Chapter 13 Exploring Space
Rocket Altitude
Altitude and time, meters and seconds
Reading Graphs:
What two variables are being graphed? In what unit is each measured?
Chapter 13 Exploring Space
Rocket Altitude
About 65 meters; about 128 meters
Reading Graphs:
What was the rocket’s altitude after 2 seconds? After 4 seconds?
Chapter 13 Exploring Space
Rocket Altitude
6 seconds
Reading Graphs:
At what time did the rocket reach its greatest altitude?
Chapter 13 Exploring Space
Rocket Altitude
The rocket’s inertia caused it to continue to rise after its fuel ran out. Eventually friction caused the rocket to slow down and gravity caused it to fall
Inferring:
Why do you think the rocket continued to rise after it ran out of fuel?
Chapter 13 Exploring Space
A Multistage Rocket
A typical multistage rocket has three stages. Each of the first two stages burns all of its fuel and then drops off. The next stage then takes over.
