,For A-Level Physics Paper 2, focus on the following key areas:
1. Mechanics and Materials:
Forces and Motion: Understand Newton's laws of motion, equations of motion (suvat equations), and
the conservation of momentum in collisions (elastic and inelastic).
Work, Energy, and Power: Know the work-energy principle, calculate kinetic and potential energy, and
understand the concept of power as the rate of energy transfer (P = W/t).
Circular Motion: Study centripetal force, centripetal acceleration, and the conditions for circular
motion (e.g., satellites and vehicles in curves).
Elasticity and Hooke’s Law: Understand the relationship between force and extension in elastic
materials and calculate the Young’s modulus.
2. Electricity:
Current, Voltage, and Resistance: Master Ohm's law (V = IR) and understand how current, voltage,
and resistance interact in both series and parallel circuits.
Power in Circuits: Know how to calculate power in an electrical circuit (P = IV, P = I²R).
Capacitance: Study the relationship between charge, voltage, and capacitance (Q = CV), and the time
constant for charging and discharging capacitors in RC circuits.
Electric Fields: Understand electric field strength, the relationship between field strength and potential,
and the force on a charge in an electric field.
3. Waves:
Wave Properties: Know the key characteristics of waves: wavelength, frequency, amplitude, and wave
speed. Understand the equation v=fλv = f\lambdav=fλ.
Wave Behavior: Study refraction, diffraction, interference, and superposition of waves. Understand
standing waves and the formation of resonant frequencies.
4. Thermal Physics:
Temperature and Heat: Understand the kinetic theory of gases, and how temperature and pressure
are related for ideal gases (PV = nRT).
Specific Heat Capacity: Study the heat required to change temperature (Q = mcΔT), and understand
latent heat during phase changes (Q = mL).
5. Nuclear Physics:
Radioactivity: Understand the properties of alpha, beta, and gamma radiation, and the concept of half-
life.
Nuclear Fission and Fusion: Study the processes of nuclear fission (used in nuclear reactors) and
nuclear fusion (energy from stars), including the energy released in these processes.
6. Practical Skills:
Experimental Techniques: Focus on key practical techniques such as data collection, error analysis, and
uncertainty calculation. Practice interpreting experimental data and drawing appropriate conclusions.
Graphical Analysis: Be comfortable with plotting graphs, analyzing trends, and calculating gradients.
Understand how to use graphical methods to derive physical quantities.

A dehumidifier cools and then condenses water vapour from the moist air.
The final temperature of the liquid water that collects in the dehumidifier is 10 °C.
Drier air leaves the dehumidifier at a temperature of 20 °C.
Table 1 compares the air flowing into and out from the dehumidifier.

moist air flowing in 0.0057
drier air flowing out 0.0037
In one hour, a volume of 960 m3 of air flows through the dehumidifier.
Assume that the density of the air remains constant at 1.25 kg m−3.
Determine how much heat energy is removed in one hour from the water vapour by
the dehumidifier.
specific heat capacity of water vapour = 1860 J kg−1 K−1
specific latent heat of vaporisation of water = 2.3 × 106 J kg−1
