Physical obstacles are barriers that can hinder movement or access in various environments. These can include natural features like mountains, rivers, or forests, as well as man-made structures such as walls, fences, or buildings. They can affect transportation, recreation, and even daily activities, making it challenging for individuals to navigate their surroundings. In many cases, physical obstacles can be overcome with the right tools or adaptations. For example, wheelchairs can help individuals with mobility challenges access areas that may have steps or uneven terrain. Additionally, bridges and ramps are often constructed to provide safe passage over or around these barriers, improving accessibility for everyone.
