Equilibrium (Mechanics)
Key Stage 5
Meaning
Equilibrium is the state of an object when the net force and net moment acting on it are zero.
About Equilibrium
- In static equilibrium, an object is at rest with no net force or moment acting on it.
- In dynamic equilibrium, an object moves with constant velocity with no net force or moment acting on it.
- Conditions for equilibrium include ∑𝐹=0 (no net force) and ∑𝜏=0 (no net moment).
- Stability of equilibrium can be classified as stable, unstable, or neutral.
