Last week we learned all about dynamics or the study of force. We learned how to make a fource dyagram with two or more arrows and a dot in the middle. Sometimes but not always there will only be one arrow and that shows that the object is moving on way. Also if one arrow is larger than the other than that means the object is going that way. We also learned that for something to be standing still you would have to have another force pulling on that one. At the end of the week we started to learn about horizontal lines on the diagram and how they show the object moving side to side. The same rules apply for the horizontal lines ecept for the fact that there may be other forces infolved than the ones on the verticail diagram. Also I found that if you apply a constant force on an object it will accelerate on it's own.
