The sections below contain links to revision notes, PowerPoint slides and extra questions to test your readiness for assessments in each of the units. If you need help to view a PowerPoint file, click here to look for the PowerPoint viewer on Microsoft’s site.  Or, if you have a Glow username and password, download a copy of Microsoft Office from the tile on your home page.  Alternatively, why not download the free LibreOffice office suite? It opens PowerPoint, Excel & Word files. You can also create your own files and save them so that you can open them in school with Microsoft Office.

Some of the pdf files have been created by converting PowerPoint files. In places where the original slide is animated, you will need to read several pages in a row to see the full slide contents.

Dynamics & Space

whole unit notes – thanks to Mr Noble for sharing his notes!

BBC Bitesize dynamics & space

vectors & scalars

You know the difference between speed & velocity, don’t you?

Here is a video guide to drawing a vector scale diagram to find displacement.

notes on vectors (pdf)

Try these relative velocity problems.

Graphs of motion

Click on the picture below to try this simulation.  Set the variables and click start.  Watch as the graphs of displacement, velocity and acceleration are drawn.

You will need java to run the simulation.

Newton’s 1st Law

animation showing effects of air resistance

Friction: here are 3 clips about friction from the BBC programme Bang goes the Theory

and look what happens when cold weather removes the friction that helps you to control your car!

Here are some videos on balanced and unbalanced forces affecting the motion of objects.  The first clip examines the forces on a cyclist as she cycles round a velodrome.

The second clip looks at the way skydivers use forces to land safely.

Newton’s 2nd law

Newton’s 3rd law

I’ve written a blog post on Newton’s third law during a rocket launch that shows Newton’s 3rd law very clearly.  There’s also a follow-up post on Newton’s third law with footage of the Apollo 11 rockets destroying the launch pad.

If you’ve read all that stuff on forces, take a break to watch the Glesga Physics Newton’s Laws video

Here is a short video about projectile motion.

orbits and gravity (animation showing planets in our solar system with some gravity information)

Curved reflectors are often used to produce a strong beam of energy in one direction. The shiny backgrounds behind the bulb of a car headlamp, torch or halogen spotlight are examples of curved reflectors.

Projectiles and Satellites

We use curved reflectors to communicate with satellites in orbit around the Earth. Signals are sent from a large curved reflector on the surface to a curved receiver on the satellite. The satellite can relay the signal to another ground station or pass it to another satellite before it is sent back to another ground station.

A geostationary satellite is not actually stationary. By rotating at the same rate as the Earth, the satellite always appears to sit in the same point in our sky. This is quite handy, since it would be a nuisance if we had to move dish aerials to follow the location of a satellite broadcasting our TV signals.

The video below is designed to show you what the view from a geostationary satellite might look like. Since the satellite and Earth rotate at the same rate, one full rotation every 24 hours, the satellite is always over the same point on the Earth’s surface.

There’s more about satellites here.

Here is a Sixty Symbols video about orbits and Yuri Gagarin – the first man in space.

Have you ever thought about explaining science topics using only the most popular 1000 words?  Here’s an attempt to describe going into space…

You are expected to know that the friction encountered by a spacecraft as it re-enters the atmosphere has the effect of transforming the vehicle’s kinetic energy into heat energy. The vehicle slows down as its kinetic energy is lost.

This article includes a photo taken from the International Space Station that shows just how high the temperature of the space shuttle’s orbiter module can get. This high temperature during re-entry is the reason those special black tiles are needed on its underside.

This short video shows a night-time re-entry over Mexico, with the orbiter on its way to land at the Kennedy Space Centre.  There are no engines running, all that heat is being produced by re-entry to the atmosphere.

I wrote a blog post about re-entry into the Earth’s atmosphere.

colour temperature line spectra summary of the information we can get from the light received from any star (surface temperature of the star, what the start is made of, etc.)

How do you find exoplanets?

How do you prepare for going into space?

The following three video clips look at the risks involved in a manned mission to Mars.

Don’t forget the danger of being hit by a piece of space junk!

Here is a diagram of the most important language for the electricity topics in this unit. You can view a larger version by clicking on the image below.

This unit contains more equations but remember that the relationship sheet you are given during the exam will have these, so don’t panic if you forget one of them.

AC and DC Electricity

Charge and Current

This article gives an introduction to ac electricity.
electrical appliances – power rating and safety features

Watch this BBC Bitesize video about the ways that fuses and RCDs help protect us from electrocution.

Current, Voltage and Resistance in series and parallel circuits.

Here is a short video about resistors.

Ohm’s Law

Resistance and Ohm’s Law

Here is another video clip about Ohm’s Law.

Ohm’s Law from Make: on Vimeo.

Notice how the presenter converts the current from mA to A before doing the calculation in his example.

There are useful set of series and parallel resistor activities here. Use the next button or follow links in the left sidebar to progress through the topic.

Energy

conservation of energy

energy, work and power

gas laws

Volume-Temperature

The professor from the brilliant periodic videos site has a clip about Lord Kelvin and the temperature scale named after him.

Kinetic Theory

Can you use the kinetic theory of gases to describe the pressure-temperature, pressure-volume or volume-temperature relationships?  If you are having difficulties with this, try reading this blog post.

Then watch the video below about a party trick involving hot air and an egg.

Now go back and listen to Molly’s explain the behaviour of the oxygen molecules once more.  Did you notice the “cause and effect” style of explaining what happens?  This is the type of answer you need to give in a question where you are asked to describe gas behaviour using the kinetic theory. Also notice that the egg is never “sucked” – suck is bad physics! (Bonus points if you spotted Molly describing air as oxygen, when it is mostly composed of nitrogen)

1. Hi, I’m revising for Nat 5 physics and the two pupil booklets have been of great use to me! Thanks a lot for providing this excellent resource 🙂

I was wondering if you have the answers to the problems in the E&E and D&S booklets, if so could you possibly send me them?

Many thanks

Amandeep

2. Is this for the past paper booklets? There are links to the answers next to the links to the questions.

• No, sorry. I got them from Mr Noble. You could try googling, he might have a set of answers online. Or maybe someone else has produced a set?

3. Okay thanks anyway!

Your site is very useful and impressive!
