Identify the forces acting on the loudspeaker and then draw them on the free body diagram. With the exception of gravity and certain other forces rarely used in first semester physics magnetism electric force. Think of which forces are acting on the body. From the center of rectangle representing cheerleader a draw a downward arrow and mark it m1g which is the weight of cheerleader a acting on him.

Two blocks two flat weighing scales hanging weight two spring scales. The drwing of free body diagram is over. If there are multiple objects of interest you will need to draw multiple diagrams identify all the forces acting directly on the object and the object exerting them.

If necessary refer to the list of forces and their description in order to understand the various force types and their appropriate symbols. Now have two people each pulling on one of them. Then determine the direction in which each force is acting.

While students are working on the worksheet with their table groups i walk around to answer any questions students might have. Free body diagram worksheet 1. The exact length of your vectors is not important but the relative length of one to the other is.
