Common mistake

Misinterpreting Free-Body Diagrams

Students often confuse the direction of force arrows in free-body diagrams, leading to incorrect interpretations of the forces acting on an object.

To fix this, students should carefully analyze the problem, ensuring they understand the direction of each force and accurately represent it with arrows in their diagrams.
