    21.1 Introduction to Buoyancy Buoyancy describes the upward force exerted by a fluid on an object that is partially or completely submerged. This force is responsible for objects appearing to weigh less in fluids and for objects floating or sinking. 21.2 Basic Understanding of Buoyancy Buoyancy occurs due to the pressure difference exerted by a…

    8.1 Introduction to Force Diagrams Force diagrams, also known as free-body diagrams, are visual representations that show the forces acting on an object. These diagrams are an essential tool in understanding and analyzing the behavior of objects under the influence of various forces. Drawing a force diagram is often step one in solving for the…

    7.1 Introduction to Forces: Push and Pull Forces are an essential concept in physics. A force can cause an object to move, stop, speed up, slow down, or change direction. They do this via a “push” or “pull” action. Forces are typically measured in Newtons There are different methods of categorizing forces. One way is…
