eating a donut



Although it may not seem like much, there are a lot of physics involved with eating a donut. First, you have to apply a force on the donut when you pick it up and raise it to your mouth. Since the average donut weighs in at about .04 kg, it takes about .4 newtons to lift a donut. it also takes roughly .4 Joules to lift a donut from the table to your head. lastly, if you bite really hard into the donut, you will exert anywhere from 500-700 newtons. that means the donut bites back with the same amount of force. So next time somebody makes fun of you for eating a donut, just tell them how much work it takes.
