Without the choices this is difficult to answer but some examples of potential energy are:
- <span>Potential Energy is any type of stored energy. It can be chemical, nuclear, gravitational, or mechanical.
- Stretching a rubber band and holding it. It has potential energy.
- Chemical energy in a battery has potential energy.
Hope this helps!</span>
Answer:
Water
Explanation:
windmills were used to bring water to farms in ancient times.
We may be positive that an object is in mechanical equilibrium if it is not rotating and experiences no acceleration.
<h3>What is
mechanical equilibrium?</h3>
There are numerous other definitions for mechanical equilibrium that are all mathematically comparable in addition to the definition in terms of force. A system is in equilibrium in terms of momentum if the component motions are all constant. If velocity is constant, the system is in equilibrium in terms of velocity. When an item is in a state of rotational mechanical equilibrium, its angular momentum is preserved and its net torque is zero. More generally, equilibrium is reached in conservative systems at a configuration space location where the gradient of the potential energy concerning the generalized coordinates is zero.
