Here are the posters produced by N5 (2016-2017) They answer the questions posed in the research task document below which was created from the Full Content Check 2016. Check them out. There are still a few to come and some need to be updated. If yours isn’t here then let me know and we’ll update.

##### Gravity Assist

In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist manoeuvre, or swing-by is the use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the path and speed of a spacecraft. This saves fuel, time, and expense. Gravity assistance can be used to increase or decrease its speed or redirect the path of a spacecraft. The “assist” is provided by the motion of the gravitating body as it pulls on the spacecraft. It was used by interplanetary probes from Mariner 10 onwards, including the two Voyager probes’ notable flybys of Jupiter and Saturn.

A gravity assist around a planet changes a spacecraft’s velocity (relative to the Sun) by entering and leaving the gravitational field of a planet. The spacecraft’s speed increases as it approaches the planet and decreases while escaping its gravitational pull. Because the planet orbits the sun, the spacecraft is affected by this motion during the manoeuver. To increase speed, the spacecraft flies with the movement of the planet (taking a small amount of the planet’s orbital energy); to decrease speed, the spacecraft flies against the movement of the planet. The sum of the kinetic energies of both bodies remains constant.

## Open Ended Space Question

1. From your knowledge of energy, what might a space exploration scientist consider when sending a machine to land safely on an extra terrestrial body? The machine must be capable of sending back some intelligible data
2. Two people are discussing satellite motion one person says:
“Satellites stay in motion because there is no gravity”
Using your knowledge of Physics comment on that response.
3. An astronaut on the international space station was quoted as saying:
“I sometimes feel like a human cannon ball.”
Using your knowledge of physics explain why he is like a cannon ball in space.
4. Recently Voyager 1, one of the first space probes launched by NASA in 1977, has now left our Solar System.

EITHER: Using your knowledge of physics, explain how this space probe was able to reach the outer planets.

OR: Using your knowledge of physics, explain how NASA might know that the probe has now left our Solar System.

OR: Using your knowledge of physics, comment on what happens next to this space probe.

5. A daytime newsreader commented that, “Looking at the stars is like looking back in time.” Use your knowledge of physics to comment on the journalist’s statement.

6. There are many parts of space that are detected by different types of telescope. Use your knowledge of physics to describe one telescope that is used in astronomy.

7. A ball rolls off from a table as shown.

Use your knowledge of physics to comment on what the ball’s horizontal distance from the edge of the table would and would not depend on.

8. A velocity-time graph of skydiver 1 is shown below

A velocity-time graph of skydiver 2is shown below

Use your knowledge of physics to explain how the second skydiver’s velocity-time graph during descent compares with that of the first skydiver.

## Mass, Weight and Weightlessness

Below is a link to an excellent website for you to check your learning about weight and weightlessness. It is probably just above N5 standard, so read through it slowly and carefully and ask if there is material you don’t understand.

## Dynamics and Space Resources

Please can you let me know which set of notes you would prefer to work from. I can copy one set (sometimes in two parts). Check the material off against the outcomes and let me know via a comment or email as to which ones you prefer. Obviously if you have a means of copying you can use more of these notes, or can read them electronically.

These are my notes. I’ve spent the day working on these but there is way more to do than I imagined. I need to sort them out, but stuff is beginning to come together.

### Revision Questions

Use the pdf file, printed from a powerpoint presentation to practice work for the D&S topic. Some space has been left so that you can record your answers on the sheets. They are saved 6 slides to a page

### Resources from other schools

I would like to thank all the schools who have produced notes that are reproduced here. Know that I am really grateful. I have a half finished set of my own notes, but don’t think I can get them suitably done in time. Be assured that at least you’ll have some excellent higher notes next year, and after those scores I am expecting a big Higher class 2017-2018!

The booklet below is an Intermediate 2 booklet and contains some material for other topics and some material is missing. It might be a good idea to get yourself a copy of this, if possible, especially if you are not a great lover of the heat section!

Here are some more notes produced for Intermediate 2. There are some good questions here, but it does not cover all of the topic we are about to complete.

I will add some cut-outs and single page resources as we go through the course. If you lose yours, you will have to print them off yourself or take a photo!
