Applying Physics to Hula Hooping

Have you spent time this summer spinning a Hula-Hoop around your waist or arm? Could you do it easily or was it difficult? Have you ever wondered how Hula-Hoops work or what makes them able to spin around a person’s waist or arm—seeming to defy gravity? The answer can be explained by physics, which can help you determine what makes an effective Hula-Hoop. In this activity you’ll get to create your own Hula-Hoops and investigate how their weights affect how they spin. Which do you think will spin better, a heavy hoop or a lighter one? Get ready to do some hula-hooping to find out! Continue reading Applying Physics to Hula Hooping
