Additional Physics – P2
In all topics, you must be able to use equations given to you. If you know what the units mean, this is really easy. In G4 there is a display
board of all of the units that you need. Take a photo of it and recreate a word-sort for yourself at home.
Topic 1 – Static and current electricity
1. What does the structure of the atom look like? Where are the protons, neutrons and electrons?
2. How is an insulator charged by friction? What happens to it’s electrons?
3. What charge is on something that has gained electrons/what charge is on something that has lost electrons?
4. What are some examples of common phenomena where electrons movement has happened?
5. What is “earthing”? How does it work?
6. How do paints and insecticide sprays link to this topic?
7. What are the dangers of electrostatic charges in everyday situations?
8. What do we meant by the term “electric current”? What about the term “current”?
9. What type of current comes out of cells and batteries? What is direct current?
Topic 2 – Controlling and using electric current
1. Where would you put and ammeter, and a voltmeter, in an electric circuit?
2. What happens to current at a junction in a circuit?
3. What does the current depend on in terms of the source?
4. What is meant by the term “potential difference” (P.D), and what are it’s units?
5. How does changing the resistance in a circuit change the current and how can you change the resistance in a circuit?
6. How does current and P.D change in filament lamps, diodes and fixed resistors?
7. What is an LDR and how does it work?
8. How does the resistance of a thermistor change with a change in temperature?
9. What energy transfer happens when electric current flows through a resistor?
10. What is colliding to cause energy transfer through a resistor?
11. What are the advantages and disadvantages of the heating effect of an electric current?
Topic 3 – Motion and forces
1. What is a vector quantity? Give four examples of this.
2. You need to be able to describe what is happening in distance time graphs, including working out the speed from the gradient.
3. You need to be able to interpret velocity/time graphs.
4. What is a free body diagram? What does it show?
5. What are reaction forces?
6. How would you calculate a resultant force?
7. How does the resultant force relate to the velocity of a body.
8. In a vacuum, what happens to the acceleration of a body?
9. Describe the forces acting on a body as it falls through the atmosphere towards the Earth.
Topic 4 – Momentum, energy, work and power
1. How would you calculate the stopping distance of a vehicle?
2. What 6 factors can affect how long it could take a vehicle to stop?
3. What is linear momentum conservation?
4. Why are bubble wraps, seat belts, crumple zones and air bags.
5. How are “work done” and “energy transferred” linked?
6. What is one watt equal to?
7. What doe the term “conservation of energy” mean?
Topic 5 – Nuclear fusion and nuclear fission.
1. Define the terms “atomic number” and “mass number”.
2. What is an ion, and how do these form?
3. What is an alpha particle? What is a beta particle? What is a gamma ray?
4. What can alpha, beta and gamma penetrate? Which one has the most penetrating power?
5. Give three examples of nuclear reactions.
6. What happens in the fission of U-235?
7. What is a controlled nuclear chain reaction, and how is it controlled? What energy transfers occur at a nuclear power station.
8. What is nuclear fusion? Explain the difference between fission and fuision.
9. Explain why nuclear fusion doesn’t happen at low temperatures
10. Link the conditions for fusion to why it’s hard to make a power station that does this.
11. What is cold fusion? Are there any other ideas that are new?
