Learners analyze the forces acting on a system and construct a free-body diagram.
After completing this tutorial, you will be able to complete the following:
A force is a push or pull, an interaction between two objects. Often, there are several forces acting on one object or system. When forces are acting upon an object, it is important to draw a free-body diagram for the object and label these forces. Some common forces found in everyday situations are:
When drawing the forces in a free-body diagram, the direction of the forces must also be indicated. Therefore, arrows are used to indicate the direction. Additionally, the magnitude of the force is represented by the length of the arrow?the longer the arrow, the stronger the force.
