COLLISIONS

Introduction

This topic is about spheres which collide with a barrier (impacts) or which collide with another sphere (collisions).  There are four main types of question:

  • Direct impacts
  • Oblique impacts
  • Direct collisions
  • Oblique collisions

Common Mistakes

• Forgetting to put the minus in front of e in NEL.
• Applying NEL to both directions, not just to the direction of impact.
• Confusing momentum and kinetic energy.
• Forgetting the definition of impulse, even though it is on Page 40 of The Mathematical Tables!
