  1. Aug 19, 2022 · Draw a free body diagram of the object. Decide which direction is positive and which is negative. Subtract the forces in the negative direction from those in the positive direction. If the problem asks for it, use the net force to find mass or acceleration.

  2. How to find the magnitude and direction of a force given the x and y components. Learn what a free-body diagram (or FBD) is, and how to draw it in 3 simple steps. Examples, as well as exercises, are included.

  3. Free-body diagrams showing these forces, their direction, and their relative magnitude are often used to depict such information. In this Lesson, The Physics Classroom discusses the details of constructing free-body diagrams. Several examples are discussed.

  4. Explain the effects with the help of a free-body diagram. Use free-body diagrams to draw position, velocity, acceleration, and force graphs, and vice versa. Explain how the graphs relate to one another. Given a scenario or a graph, sketch all four graphs.

  5. You will need to analyze the motion of an object and create a free body diagram of the relative forces in order to derive the force equations. We learned in the kinematics section how to analyze motion without any concern about the forces that caused the motion. The infographic below describes the relationship between force and accelertion.

  6. Once we have drawn an accurate free-body diagram, we can apply Newtons first law if the body is in equilibrium (balanced forces; that is, F net = 0 F net = 0) or Newton’s second law if the body is accelerating (unbalanced force; that is, F net ≠ 0 F net ≠ 0).

  8. A free-body diagram is a sketch of a body, a portion of a body, or two or more bodies completely isolated from all other bodies. It shows the external forces and couples acting on the system (drawn carefully with respect to location, direction and magnitude).
