This PowerPoint lesson introduces contact forces and at-a-distance forces using clear explanations, real-world examples, diagrams, and photos to support student understanding. Students are introduced to vectors, the Newton (unit of force), and free-body diagrams as part of the lesson. Using the guided slides, students learn to define and categorize the following forces: normal force, applied force, gravitational force, tension force, friction force, electrical force, magnetic force, spring f
