Equilibrium | Definition & Facts | Britannica
Equilibrium, in physics, the condition of a system when neither its state of motion nor its internal energy state tends to change with time. A simple mechanical body is said to be in equilibrium if it experiences neither linear acceleration nor angular acceleration; unless it is disturbed by an.
Equilibrium and Statics - The Physics Classroom
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.
Mechanical equilibrium - Wikipedia
More generally in conservative systems, equilibrium is established at a point in configuration space where the gradient of the potential energy with respect to the generalized coordinates is zero. If a particle in equilibrium has zero velocity, that particle is in static equilibrium.
12.2: Conditions for Static Equilibrium - Physics LibreTexts
OpenStax. Learning Objectives. Identify the physical conditions of static equilibrium. Draw a free-body diagram for a rigid body acted on by forces. Explain how the conditions for equilibrium allow us to solve statics problems.
9.3: Conditions for Equilibrium - Physics LibreTexts
Jun 17, 2019 · A rotating body or system can be in equilibrium if its rate of rotation is constant and remains unchanged by the forces acting on it. The magnitude of torque about a axis of rotation is defined to be \(\mathrm{τ=rF \sin θ}\). In equilibrium, the net …
11.7: Equilibrium - Physics LibreTexts
Mar 28, 2024 · Dynamic equilibrium. 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).
12.2 Examples of Static Equilibrium - University Physics
Set up and solve static equilibrium conditions for objects in equilibrium in various physical situations. All examples in this chapter are planar problems. Accordingly, we use equilibrium conditions in the component form of Equation 12.7 to Equation 12.9.

Equilibrium - Isaac Physics
Equilibrium. For an object or system to be in equilibrium, the sum of the forces acting on it must be zero. F tot = 0. Mathematically this is written as: i∑ F i =0. The moments or torques around any point on the object or system must also sum to zero. τ tot =0 or i∑ τ i = 0. GCSE. A Level. A Level.
Physics Video Tutorial - Equilibrium - The Physics Classroom
This video tutorial lesson explains what is meant by the term equilibrium and shows how to conduct a mathematical analysis of the force vectors to determine if an object is at equilibrium.
