Explanation:

An intentional injury is one that was caused by a human being who intended to cause an injury, that is, this injury was done on purpose in someone who intended to hurt another person. All types of violence result in intentional injuries. The laws that can prevent this kind of injury, for example, are the Armed robbery laws.

On the other hand, an Unintentional injury is an injury caused without intending to hurt anyone. It is an accident that has occurred through a sudden and unplanned event that causes or may cause injury to persons or damage to buildings, facilities, materials or the environment. As an example of laws that can prevent this kind of injury, we can cite Bicycle helmet laws.
