This comprehensive PowerPoint covers Physical Quantities, S.I. Units, Errors, and Vectors for IGCSE/GCSE Physics, aligning with curriculum objectives. It includes:

• S.I. Units: Base and derived units (e.g., power, voltage) and prefixes.
• Measurement Techniques: Estimating lengths, masses, and time intervals using real-world benchmarks.
• Errors & Uncertainty: Differentiates between random/systematic errors, calculates absolute/percentage uncertainty, and combines uncertainties in calculations.
• Scalars & Vectors: Definitions, examples (e.g., force, velocity), and graphical methods (triangle/parallelogram rules) for vector addition/resolution.
• Practical Applications: Relative velocity problems (e.g., wind impact on flight) and resolving forces on slopes.

Engaging features:

• Interactive starters and group activities (e.g., scalar/vector sorting).
• Step-by-step uncertainty calculations with worked examples.
• Visual aids: Scale diagrams for vector problems and error analysis graphs.

Perfect for teachers seeking structured lessons with real-world relevance and students mastering foundational physics concepts.

Keywords: AS Physics, S.I. units, scalars and vectors, measurement uncertainty, error analysis, vector addition, derived units, absolute uncertainty, relative velocity.
