You are expected to use a scientific calculator where appropriate.
A Data and Formulae Booklet is provided as a loose insert.
,For A-Level Physics Paper 1, focus on the following key areas:
1. Measurement and Errors:
Units and Standard Form: Familiarize yourself with SI units, converting between units, and using
standard form for very large or small numbers.
Significant Figures and Rounding: Understand how to use significant figures to report precise
measurements and how to round appropriately.
2. Forces and Motion:
Kinematics: Study the suvat equations for uniform acceleration, and be able to calculate
displacement, velocity, and time.
Newton’s Laws: Understand the three laws of motion and how they apply to different situations, such
as forces acting on an object.
Momentum: Learn the concept of momentum and the principle of its conservation during collisions
(elastic and inelastic).
Work, Energy, and Power: Understand the work-energy principle, calculate kinetic and potential
energy, and understand how power is related to energy transfer.
3. Waves:
Wave Properties: Understand key features of waves, such as amplitude, frequency, wavelength, and
speed, and how they are related (v = fλ).
Wave Behavior: Study phenomena such as reflection, refraction, diffraction, and interference, and
apply these concepts to solve problems.
Sound Waves: Understand the properties of sound waves and their applications, including the Doppler
effect.
4. Electricity:
Current, Voltage, and Resistance: Study Ohm’s Law (V = IR), and understand how current and
voltage relate in both series and parallel circuits.
Power: Understand the formulas for electrical power (P = IV, P = I²R) and how to calculate power in a
circuit.
5. Materials:
Stress and Strain: Understand the relationship between force and extension in elastic materials, and
calculate the Young’s Modulus.
Elastic and Plastic Deformation: Study the difference between elastic and plastic deformation and be
able to interpret stress-strain graphs.
6. Nuclear Physics:
Radioactivity: Understand the three types of radiation (alpha, beta, gamma), their properties, and their
ability to penetrate materials.
Half-life and Decay: Learn to calculate half-life and understand the concepts of nuclear decay and the
decay constant.
By focusing on these areas, you'll be well-prepared for A-Level Physics Paper 1, which covers foundational
physics principles and their practical applications.
