CONNECTED PARTICLES

Introduction

This topic is about objects which are connected by strings, or which travel across surfaces (both smooth and rough).  It also involves wedges.  The key thing to remember is the formula F = ma. In this equation, F represents the total force along the line in which the particle travels;  m is the mass ; a is the acceleration of the particle.

There are four main types of question:

  • Particles with pulleys
  • Particles on rough surfaces
  • Relative accelerations
  • Wedges
