Equilibrium

Types of Equilibrium

  1. Static Equilibrium

  • Occurs when an object is at rest and remains at rest.

  • The sum of forces and the sum of torques acting on the object are zero.

  • Example: A book lying flat on a table.

  1. Dynamic Equilibrium

  • Occurs when an object is moving at a constant velocity.

  • The sum of forces acting on the object remains balanced, resulting in no acceleration.

  • Example: A car driving at a Constant speed on a straight road.

  1. Stable Equilibrium

  • A state where a system tends to return to its original position after a slight disturbance.

  • Example: A ball resting at the bottom of a bowl.

  1. Unstable Equilibrium

  • A state where a system moves away from its original position after a slight disturbance.

  • Example: A ball balanced on top of a hill.

  1. Neutral Equilibrium

  • A state where it can be displaced without returning to its original position, and it stays in the new position.

  • Example: A ball rolling on a flat surface.
