Force:Force is any interaction that can change an object's state of motion. When dealing with blocks of mass, forces such as gravity, friction, or applied forces are often considered.
Newton's Laws: Newton's laws describe the relationship between the motion of an object and the forces acting upon it. Blocks of mass are commonly used to illustrate these laws in action.
Free Body Diagram:A free body diagram is a visual representation that shows all the forces acting on an object. Blocks of mass are frequently depicted in free body diagrams to analyze their motion under different forces.
