1. Kinetic Energy
This video goes through the meaning of kinetic energy and looks at the equation for calculating kinetic energy.
2. Gravitational Potential Energy
This video gives a description of what gravitational potential energy is and the equation that is used to calculate it.
3. Kinetic Energy and Gravitational Potential Energy
This video gives an example of how kinetic energy and gravitational potential can be linked and it goes through and example of calculations involving both of these energy stores.
4. Elastic Potential Energy
Elastic potential energy is an energy store associated with elastic objects such as springs. Here we look at elastic potential energy and the equation used to calculate it.
5. Specific Heat Capacity
This video explains the meaning of specific heat capacity, looks at the equations and goes through some practise questions for specific heat capacity.
6. Power
This video explains the meaning of the term 'power' in physics and gives some practise questions for using the power equation.
7. Energy Transfers in Systems
This video looks at the idea of systems in physics (a group of objects that interact) and how energy is transferred in closed systems
8. Reducing Unwanted Energy Transfers
This video looks at ways of reducing unwanted energy transfers and also goes through a thermal conductivity experiment that is mentioned on the spec.
9. Efficiency
This video goes through the meaning of the term efficiency, gives some practise on how to use the equation and has a useful summary at the end.
10. National and Global Energy Resources
This video explains the difference between renewable and non-renewable energy sources and gives advantages and disadvantages of both.
Electricity
11. Standard Circuit Diagram Symbols
This video goes through the standard circuit symbols that you need to know for your GCSE physics and helps you recognise the different ones as diagrams.
12. Electrical Charge and Current
This video goes to the meaning of the word 'charge' and introduces an equation for calculating charge.
13. Current Resistance and Potential Difference
This video goes to the relationship between current, potential difference and resistance and gives the equation that links the three.
14. Resistors
This video describes the relationship between potential difference and current for a fixed resistor, a lamp and a diode
15. Resistors II
This video describes the current versus potential difference relationship for a thermistor and a light dependent resistor.
16. Series and Parallel Circuits
This video describes the features of series and parallel circuits
17. Mains Electricity
Here we talk about the features of mains electricity and describe the structure of a three-pin plug which supplies electricity through a three-core cable
18. Mains Electricity II
This video explains the function of a fuse in a three pin plug and how it functions as a safety device.
19. Power
This video explains the meaning of electrical power and goes through two equations that you need to know and remember
20. Energy Transfers in Everyday Devices
This video describes how energy can be transferred in everyday devices and gives two equations that you should be able to use.
21. The National Grid
This video goes through the structure of the National Grid system including the role of step up and step down transformers
22. Static Electricity - Physics Only
Here we learn about the the way objects can become electrically charged and exert forces as a result of this and how charge is caused by the movement of electrons.
23. Electric Fields - Physics Only
This video goes through the meaning of electric charge and factors that affect the electric field strength around charged objects.
Particle Model of Matter
24. Density of Materials Model and State Symbols
Here we look at the meaning of density and explain what it is in terms of the particles in a substance. We also practise using the density equation.
25. Changes of State
In this video, we look at the states of matter and describe the changes in terms of energy. We also learn the key words related to change of state.
26. Internal Energy
Internal energy is a new addition to the specification for the 9-1 GCSE Physics course. Here we look at the meaning of internal energy and factors that can change it.
27. Specific Latent Heat
This video explains what specific latent heat is, the graphs for melting and boiling substances and looks at example of where the equation can be used.
28. Particle Motion in Gases
Here we explain how the motion of the molecules in a gas is related to both its temperature and its pressure and the relation between the temperature of a gas and its pressure at constant volume.
29. Pressure in Gases - Physics only
Here we learn how to calculate the change in the pressure of a gas or the volume of a gas (a fixed mass held at constant temperature) when either the pressure or volume is increased or decreased.
Atomic Structure
30. The Structure of an Atom and Isotopes
Here we recap on the structure of atoms, what isotopes are and explain why the electron arrangements of atoms may change with the absorption of electromagnetic radiation.
31. Development of the Atom Model
The video explains the idea that new experimental evidence may lead to a scientific model being changed or replaced. This is a very good example of how a scientific model has developed and changed over time.
32. Radioactive Decay and Nuclear Radiation
Here we learn the properties of alpha particles, beta particles and gamma rays related to their penetration through materials, their range in air and ionising power
33. Nuclear Equations
In this video, we learn how to use the names and symbols of common nuclei and particles to write balanced equations that show single alpha (α) and beta (β) decay.
34.Half lives and the Random Nature of Radioactive Decay
Here we learn how to explain the concept of half-life and how it is related to the random nature of radioactive decay and be able to determine the half-life of a radioactive isotope from given information
35. Radioactive Contamination
Here we look at radiation and compare the hazards associated with contamination and irradiation
36. Background Radiation - Physics only
This video goes through the meaning of background radiation and what the sources are.
37. Medical Uses of Radiation - Physics only
In this video, we describe and evaluate the uses of nuclear radiations for exploration of internal organs, and for control or destruction of unwanted tissue.
38. Nuclear Fission - Physics only
In this video, we learn how to draw/interpret diagrams representing nuclear fission and how a chain reaction may occur.
39. Nuclear Fusion - Physics only
Here we look at nuclear fusion is the joining of two light nuclei to form a heavier nucleus and evaluate its potential for generating electricity.
