Movement and locomotion are similar but distinct concepts. Movement is any change in the position of an object, while locomotion is the ability to move from one location to another. Movement can be intentional or unintentional, while locomotion is always intentional. Movement can involve a change of position, direction, or orientation, while locomotion is always a change of location. Movement can also involve the use of muscles or other forms of energy, while locomotion requires the use of muscles, either directly or indirectly.
