In physics, equilibrium refers to a state where a system experiences no net change over time, meaning all forces and moments are balanced. This can be static, where objects are at rest, or dynamic, where objects move at constant velocity without acceleration.

Equilibrium In Physics

Equilibrium refers to a state where opposing forces or influences are balanced, resulting in a stable system. It is a fundamental concept across various disciplines, indicating a condition where variables remain constant over time unless disturbed by external factors.

Equilibrium

No net change over time

Balanced forces

Static equilibrium occurs when an object is at rest or moving at a constant velocity, with all the forces and torques acting on it balanced, resulting in no net force or torque. This state is crucial in engineering and physics to ensure structures and systems remain stable and unchanging over time.

Static Equilibrium

Objects at rest

Dynamic equilibrium occurs in a system where two opposing processes happen at the same rate, resulting in no net change in the system's state. It is a hallmark of reversible reactions, where reactants and products are continuously interconverted but their concentrations remain constant over time.

Dynamic Equilibrium

Constant Velocity

Acceleration is the rate of change of velocity of an object with respect to time, and it is a vector quantity that has both magnitude and direction. It is a fundamental concept in physics that explains how the motion of objects changes due to forces acting upon them, often described by Newton's Second Law of Motion.
