What is dynamic equilibrium in laymen's terms?

In summary, the problem involves a 2.0 kg wood box sliding down a vertical wood wall with a coefficient of kinetic friction of 0.200. To keep the box moving at a constant speed, the net force in the vertical direction must be 0, as the box is in dynamic equilibrium. Dynamic equilibrium means there are no accelerations, even though the box is in motion. The sum of the forces in each direction must be zero for dynamic equilibrium to occur.

I was receiving help for the following problem...

The 2.0 kg wood box in the figureslides down a vertical wood wall while you push on it at a 45 ∘ angle. The coefficient of kinetic friction of wood on wood is μk = 0.200. What magnitude of force should you apply to cause the box to slide down at a constant speed?

And I was told to set the F(net) of the y-axis to 0 because the box is in dynamic equilibrium.
What exactly does dynamic equilibrium mean? I want to understand so I'll know to use it in a different problem.

FAQ: What is dynamic equilibrium in laymen's terms?

What is dynamic equilibrium?

Dynamic equilibrium is a state of balance or stability in a system where the rate of change in one direction is equal to the rate of change in the opposite direction.

How is dynamic equilibrium different from static equilibrium?

Dynamic equilibrium involves continuous movement and change, while static equilibrium is a state of rest or no movement.

What are some examples of dynamic equilibrium in everyday life?

Examples of dynamic equilibrium include the water cycle, where water evaporates from the surface of the earth and is then returned through precipitation, and the balance of oxygen and carbon dioxide in our bodies through breathing.

How is dynamic equilibrium important in science?

Dynamic equilibrium is important in science because it helps us understand how natural systems and processes maintain balance and stability. It is also a key concept in many fields of science, including physics, chemistry, and biology.

Can dynamic equilibrium be disrupted or changed?

Yes, dynamic equilibrium can be disrupted or changed by external factors, such as changes in temperature, pressure, or concentration. When this happens, the system will adjust to try to restore balance and reach a new equilibrium state.
