UNIT OVERVIEW

This revision unit covers the five topics from Term 1:

• Vectors in Two Dimensions
• Newton's Laws and Application
• Newton's Law of Universal Gravitation
• Molecular Structure
• Intermolecular Forces

What you will do:

• Recap essential concepts, formulas, and definitions
• Work through mixed practice problems (easy → hard)
• Tackle exam-style questions with model answers
• Identify common mistakes before they cost you marks

By the end, you should be able to:

• Resolve and add vectors using components
• Apply Newton's Laws to horizontal surfaces, inclines, and pulley systems
• Calculate gravitational forces and field strength
• Draw Lewis structures and predict molecular shapes
• Explain physical properties using intermolecular forces
