Force

In Physics, we learned about force.  A force is a push or a pull.  This week we learned  about how forces affect objects.  In learning this, we used free body diagrams.  In the picture above, there is my contact solution box resting on my dresser.  This box can stay at rest because it is balanced and no outside forces are acting upon it.  The forces which make this object balanced are its own weight (mg) pushing down and the normal force (N) pushing up.  These two forces equally pushing against each other is what makes the object balanced.  Right next to my picture of the box at rest on the dresser, there is my free body diagram.  Free body diagrams (FBD) helps us to see the forces and how they are affecting the object.  There are two arrows in my FBD, which are the weight and the normal force.  This is another way of explaining how the object is balanced.
