A2 Edexcel Physics – Further Mechanics: Momentum & Impulse | Unit 4

Welcome to the first video in our A2 Edexcel Physics Unit 4: Further Mechanics playlist! In this lesson, we'll explore momentum (p = mv), impulse (I = FΔt = Δp), and how they're applied in conservation of momentum, inelastic and elastic collisions, and real-world physics scenarios.

* What You'll Learn:*

The definition of momentum as a vector quantity (mass × velocity), with units of kg m/s.

The concept of impulse—how force acting over time changes momentum—and its expression I = F Δt = Δp.

How Newton’s second law links force and change in momentum.

Examples of elastic versus inelastic collisions, and how kinetic energy may or may not be conserved.

Real-world applications: why hailstones impart greater impulse than raindrops—practical insight for exam success.

If you're revising A-level Edexcel A2 Physics or preparing for International Edexcel, this video provides essential explanations aligned with the Unit 4 Further Mechanics syllabus.
