Definition: The word "actuation" in physics refers to the energy released by an applied force as a result of the force acting on an object. The concept of actuation can be explained through the law of conservation of energy, which states that the total energy of a closed system remains constant over time. If an external force is applied to an object, it will create a displacement within that object. When this motion is accompanied by a change in the state of the object's internal forces (i.e., the objects' position), the actuation or force of the external force results from that displacement. The rate at which energy is being converted into work (the total amount of energy released) depends on the specific properties and forces involved. For example, when an object is accelerating, its kinetic energy increases, while its potential energy decreases, resulting in a net increase in energy. Conversely, when an object is decelerating, its kinetic energy decreases, but its potential energy increases (and vice versa), leading to a decrease in energy. In summary, actuation refers to the conversion of internal forces into external energies through displacement, which results from that force's application on an object. The rate at which this occurs depends on the specific properties and forces involved, and it can be measured using the work-energy theorem or other relevant equations.
