![]() ![]() The forces all act perpendicularly to the area. With a force □ acting at every point within that area. We can do this by multiplying the formula by □:Ĭonsidering the formula this way, we can say that a pressure □ on an area □ is associated We can express the relationship between force, pressure, and perpendicular area then asĪ different way of understanding the relationship between force and pressure is to make force the subject of the formula. This is the case as multiplying a vector quantity by a scalar quantity results in another vector quantity. When relating force, area, and pressure, we see that multiplying the area perpendicular to the force by the pressure givesĪs both force and area are considered as vector quantities when related this way, we see that pressure must be a scalar That is perpendicular to the area changes how the quantity area is used. ![]() This is theĬase even though area is a scalar quantity when it is not related to the direction of a force. We can then consider both a force □ and an area □ to be vector quantities. ![]()
