Momentum and Newton's laws of motion

Welcome to **Momentum and Newton's Laws of Motion**! This core topic unpacks how forces shape the movement of everything around us. From understanding why a heavy truck is harder to stop, to the fundamental rules governing all interactions, you'll master the **vector** quantity of **momentum** and the three iconic laws that define classical mechanics. This pilot aligns with **Senpai Corner** AS notes (2025–2027) for topic **3.1**.

Need to know

What you need to know

  • Momentum ($p$) is a vector quantity with units kg m/s or Ns.
  • The direction of momentum is the same as the direction of velocity.
  • An object at rest has zero momentum.
