Using the be as free body different types of forces that you have learned about (and that are listed on your first homework assignment-DRAW and LABEL the forces acting on the objects described (You do not need to draw the object, just a box or a dot that represents the object): EXAMPLE: A flying snake (yes they exist!)is gliding from a tree to the ground at constant velocity. Consider air resistance. Drag Force (Friction) Gravitational Force (weight) There are 2 forces acting on the flying snake. The drag force acting up and the gravitational force (or weight) acting downward. The flying snake might be moving diagonally, but there are no forces acting to the left or right so they will not appear on the force diagram. The arrows are the same length because the snake is moving at a constant velocity. This means that it is not accelerating and by Newton's Second Law the net force must be zero. Remember that the relative size of the arrows matters! Also, label your forces. a. A rightward force is applied to your physics book in order to move it across a desk with a rightward acceleration. Do not include frictional forces. Neglect air resistance. TEN Fapp IF grav These are diagrams that represent the magnitude and direction of the forces acting on an object.
