Learn how to draw a free-body diagram for use in solving physics problems. Every problem in physics begins with drawing a free body diagram because that is how we represent all forces acting on an object. By drawing the forces acting on a body, we can write down newton's second law of motion more efficiently. Newton's 2nd law states that F=ma, where the sum of the forces is on the left side. Writing a diagram of forces on an object helps us write down the sum of all forces acting on a body when using Newton's Laws of Motion.
