Equilibrium conditions
What Equilibrium conditions means in Physics A-Level, as defined for AQA, OCR.
Definitions of Equilibrium conditions
Exam boards and our study guides word this term in slightly different ways. Learn the version your board uses.
Check what you remember
Read the wording for your board, then hide it and explain Equilibrium conditions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
The resultant force acting on the object is zero and the resultant torque about any point is zero, so there is no linear acceleration and no angular acceleration.
A point is in equilibrium when the resultant force on it is zero, so the vector sum of the forces is zero.
