En esta sesión te ayudaremos a preparar el tercer examen, Paper 3, de A Level Physics.
Hemos elegido un montón de preguntas (especialmente, varias muy difíciles) sobre los temas que van a caer en el examen, prestando especial atención a las 16 Core Practicals. Según las indicaciones de Edexcel, esto es lo que tienes que saber…
- Core Practical 1: Determine the acceleration of a freely falling object.
- Core Practical 2: Determine the electrical resistivity of a material.
- Core Practical 3: Determine the e.m.f. and internal resistance of an electrical cell.
- Core Practical 4: Use a falling-ball method to determine the viscosity of a liquid.
- Core Practical 5: Determine the Young modulus of a material.
- Core Practical 6: Determine the speed of sound in air using a 2-beam oscilloscope, signal generator, speaker and microphone.
- Core Practical 7: Investigate the effects of length, tension and mass per unit length on the frequency of a vibrating string or wire.
- Core Practical 8: Determine the wavelength of light from a laser or other light source using a diffraction grating.
- Core Practical 9: Investigate the relationship between the force exerted on an object and its change of momentum.
- Core Practical 10: Use ICT to analyse collisions between small spheres, e.g. ball bearings on a table top.
- Core Practical 11: Use an oscilloscope or data logger to display and analyse the potential difference (p.d.) across a capacitor as it charges and discharges through a resistor.
- Core Practical 12: Calibrate a thermistor in a potential divider circuit as a thermostat.
- Core Practical 13: Determine the specific latent heat of a phase change.
- Core Practical 14: Investigate the relationship between pressure and volume of a gas at fixed temperature.
- Core Practical 15: Investigate the absorption of gamma radiation by lead.
- Core Practical 16: Determine the value of an unknown mass using the resonant frequencies of the oscillation of known masses.
De manera transversal a estos temas, practicaremos todos los tipos de preguntas, haciendo hincapié en las más difíciles: diseñar e interpretar experimentos, analizar gráficos, resolver cálculos… Todo ello, orientado al examen y a que obtengas la mejor nota posible.
Y si tienes dudas, ¡tráetelas! Cuéntanoslo antes de la clase si deseas practicar algún ejercicio en concreto, o tráete directamente tus ejercicios de Paper 3 y consulta todas tus dudas.
