Today when I got home from school, I went and sat down at the couch. All of a sudden, the couch slid backwards. I need to come up with a solution.
First we need to ask a question and define the problem. My couch is on a hardwood floor, not carpet. This means that my couch, which is very light, will want to slide everywhere. How could I make a piece of furniture move without getting new flooring?
Here's a rough model of the couch's legs. I will try different materials on the bottom these legs before placing them on the big couch.
Now I have added three different materials to the legs. I have plastic on one (white), rubber on another one (black), and felt on the last one (light brown).
Now I need to plan and execute an investigation. I will tie a rope to all of these legs and pull them. I will then measure the amount of force needed to move each and record them one foot.
I also made a hypothesis. It states that if the type of material used on the legs affects the amount of friction outputted, then the rubber material will take the most amount of force to get it to move one
Now its time to pull all of them. I'll get back to you once this process has been completed.
