N (cid:166) (cid:173) (cid:176) (cid:32) (cid:166) (cid:174) (cid:176)(cid:175) Drawing all external force acting on an object: a three way tug-on-war: Identify the system (cid:120) for the system: (cid:120) (cid:120) draw a close curve around the system (cid:120) name and label each contact force (cid:120) name and label long range force. Identify all forces acting on the object (cid:120) for the free body diagram: (cid:120) (cid:120) draw a coordinate system (cid:120) represent the object as a dot at the origin of the coordinate (cid:120) draw vectors for the identified forces. 1: a car is being towed up a 20o slope at constant velocity. Draw free body diagram: a skier is pulls up a snow-covered hill by a tow rope at a constant speed. Draw free body diagram: a file cabinet in the back of a dump truck.
