Connected Bodies - Ropes & Tow Bar (AQA A-Level Mathematics): Flashcards

Every force has an equal and opposite reaction force

Tension acts in opposite directions on connected objects

Same magnitude but opposite direction

All connected bodies have the same acceleration

Draw separate free body diagrams for each object

It adds no extra weight to the particles

Ensures both particles accelerate at the same rate

Write separate equations for each object

$3 \, \text{ms}^{-2}$

$15 \, \text{N}$
