AQA Required Practicals | A Level Physics

These videos are a summary of each of the required practicals you are required to complete as part of the AQA course. They include the theory, equipment, safety considerations, and measurements to be taken.

You may find that with the equipment at your school there are some slight variations to the method and how you analyse your data.

1. Stationary Waves

2. Double Slit

2. Diffraction Grating

3. 'g' by Freefall

4. Young Modulus

5. Resistivity

6. Internal Resistance

Required Practicals

7. Mass-Spring System

Investigation into the variation of the frequency of stationary waves on a string with length, tension and mass per unit length of the string.

2. Interference (Double Slit)

Investigation of interference effects to include the Young’s slit experiment.

2. Interference (Diffraction Grating)

Investigation of interference effects to include a diffraction grating.

3. 'g' by Freefall

Determination of g by a free-fall method

4. Young Modulus

Determination of the Young modulus by a simple method.

5. Resistivity

Determination of resistivity of a wire using a micrometer, ammeter and voltmeter.

6. Internal Resistance

Investigation of the EMF and internal resistance of electric cells and batteries by measuring the variation of the terminal pd of the cell with current in it.

7. SHM (Mass-Spring System)

Investigation into simple harmonic motion using a mass–spring system.

7. SHM (Pendulum)

Investigation into simple harmonic motion using a simple pendulum.

8. Gases

Investigation of Boyle’s (constant temperature) law and Charles’s (constant pressure) law for a gas.

9. Capacitor Discharge

Investigation of the charge and discharge of capacitors. Analysis techniques should include log-linear plotting leading to a determination of the time constant RC.

10. Force on a Wire

Investigate how the force on a wire varies with flux density, current and length of wire using a top pan balance.

11. Flux Linkage

Investigate, using a search coil and oscilloscope, the effect on magnetic flux linkage of varying the angle between a search coil and magnetic field direction.

12. Gamma Radiation

Investigation of the inverse-square law for gamma radiation.
