The sense of equilibrium responds to movements of the head. It is divided into two types--static and dynamic equilibrium. Describe and give an example of these two types of equilibrium. Select all the statements that accurately describe equilibrium.

Answer: Static equilibrium is simply described as one in which all forces acting on an object are balanced which implies that there is no resultant forces. And the object is not in motion releative to the reference plane.i.e the object does not have a velocity.

While

Dynamic equilibrium is type of equilibrium in which all the forces acting on an object are balanced but the object it moving, i.e there exist a veleocity.

Explanation:

Equilibrium simply means, forces are in balance. i.e the net force should be zero.

It can further explained forces acting downward and acting upward, and forces acting right and acting left should be equal in magnitude.

1) dynamic equilibrium can be described as the one in which the reactants are converted to products and products are converted to reactants at an equal and constant rate. Equilibrium is the state of equal, opposite rates, not equal concentrations.

Examples of dynamic equilibrium are; a)a car moving at constant velocity, b)a fan rotating at uniform speed

2)Static equilibrium is the one in which the rate of forward process is equal to reverse process.It is usually regarded as MECHANICAL EQUILIBRIUM because it occurs when all particles in the reaction are at rest and there is no motion between reactants and products.

Static equilibrium can be noticed when there is a steady-state in a system that is the dynamic forces are not acting on the potential energies of the reverse and forward reactions.

An example of static equilibrium is when graphite turn into diamond, and it is illustrated as

C(diamond) ⇌ C(graphite)
