Shearing force refers to the force applied when sliding or moving someone across a surface (e.g. a bed or chair) without proper lifting techniques. It can cause injury to the skin and underlying tissues due to friction and tearing. It is important to lift individuals using proper body mechanics to prevent shearing forces.

What is meant by shearing forces in pressure damage?
Shearing forces in pressure damage refer to the internal tissue damage caused by two surfaces moving in opposite directions, stretching and tearing tissue in between. Shearing forces can lead to deformation and disruption of blood vessels, resulting in reduced blood flow and tissue damage. It is a common mechanism of injury in pressure ulcers.
What is meant when someone says that an object falls down?
When someone says that an object falls down, it means that the object is moving in the direction of gravity, typically from a higher position to a lower position without any external force supporting it.
What is meant by centripetal force and why does such a force not work in circular orbit?
Centripetal force is the force that keeps an object moving in a circular path. It always acts towards the center of the circle. In a circular orbit, the centripetal force is provided by the gravitational force between the orbiting object and the object it is moving around. If there were no central force, the object would move in a straight line tangent to the circle.
What is tangentically force?
It seems there may be a misunderstanding or typo in the term "tangentically force." If you meant "tangential force," it is a force that acts perpendicular to the direction of an object's motion, causing it to change direction without affecting its speed. Let me know if you meant something different.
What is meant by centrifugal force?
Centrifugal force is the apparent outward force that acts on an object moving in a circular path. It is not a real force, but rather the result of inertia causing an object to move in a straight line while the circular path changes around it.
