Learn about equilibrium in physics, the condition of a system when its state of motion or internal energy does not change. Find out the different types of equilibrium, such as mechanical, static, stable and unstable, and see examples and applications.
In Physics, equilibrium is the state in which all the individual forces (and torques) exerted upon an object are balanced. This principle is applied to the analysis of objects in static equilibrium. Numerous examples are worked through on this Tutorial page.
11.7: Equilibrium. Page ID. In this section, we consider the conditions under which an object is in static or dynamic equilibrium. An object is in equilibrium if it does not rotate when viewed in a frame of reference where the object’s center of mass is stationary (or moving at constant velocity).
First Condition of Equilibrium. For an object to be in equilibrium, it must be experiencing no acceleration. This means that both the net force and the net torque on the object must be zero. Here we will discuss the first condition, that of zero net force. In the form of an equation, this first condition is: Fnet = 0.
The first equilibrium condition, Equation 12.2.2, is the equilibrium condition for forces, which we encountered when studying applications of Newton’s laws. This vector equation is equivalent to the following three scalar equations for the components of the net force: ∑ k Fkx = 0, ∑ k Fky = 0, ∑ k Fkz = 0.
Learn what equilibrium means in different branches of physics, such as mechanics, thermodynamics, and radioactivity. Find out how equilibrium is related to the transfer of energy, force, and temperature between systems.
Equilibrium is a general concept that can refer to states of… static equilibrium, which includes… translational equilibrium (the equilibrium of forces) rotational equilibrium (the equilibrium of torques) dynamic equilibrium, which includes but is not limited to… thermodynamic equilibrium (the equilibrium of internal energy transfer)
