How do you distinguish between stable and unstable equilibrium?

Answer»

Stable Kquilibrium:

  • The body tries to come back to equilibrium if slightly disturbed and released. 
  • The center of mass of the body shifts slightly higher if disturbed from equilibrium. 
  • Potential energy of the body is minimum and it increases if disturbed.

Unstable Equilibrium: 

  • The body cannot come back to equilibrium if slightly disturbed and released. 
  • The center of mass of the body shifts slightly lower if disturbed from equilibrium. 
  • Potential energy of the body is not minimum and it decreases if disturbed
