Every fish in the net can push with a certain amount of force, lets call it 1 N. If there are 100 fish in the net, with 25 swimming up, 25 down, 25 left, and 25 right they all work against each other like in tug o' war. In this situation the net force is 0 N. However, if all 100 of the fish swim down then they are working together. In this situation the net has a force of 100 N down. When we use the term "net force" we mean the total effect of all the forces acting on an object. There may be ten forces acting on an object, but there is one overall effect, described by the net force.
Use the comment section to give other good examples of net force. Feel free to include links to videos/pictures but you must give some kind of description of the forces acting in your example. There may be awards for the best examples/explanations.
Hey mr quinn,
ReplyDeletefor number 4 i have the entire chart with x and y labeled and i found the change in both F1 and Fg but when i plug them in to the Fnet= square root i am getting an answer of around 7.2. Any thoughts of what i might have missed or passed over? Thanks
Luke 7.2 N is correct. Not sure why there is a different answer on the blog. My mistake.
