A cheap and accurate technique of measuring the rolling time of cylinders Phys. Educ. Pub Date : 2021-02-18 N Panagiotides
Measuring time of motion using photogates is a good solution when the moving object has plane surfaces or when you can put upon it a plane surface object, which acts as a beam stopper. There are however situations where other devices, and in particular micro-switches, although they are much cheaper than photogates, perform at least as well as photogates. In this frontline, I describe how we can construct

Kundt’s tube is a popular experiment commonly used in schools, in which standing sound waves are made visible inside a glass tube. A fine powder is stirred up in areas of high sound particle velocities, so that one can measure the wavelength of the sound waves by examining the patterns created. In this way, the ‘invisible’ can be made visible. However, when looking at educational contexts, Kundt’s

Physics of a hula hoop Phys. Educ. Pub Date : 2021-01-28 Rod Cross
A hula hoop rotating around a person’s waist is an example of circular motion where the centripetal force on the hoop is directed towards the centre of the circle rather than the centre of the hoop. The friction force on the hoop is relatively small by comparison since the hoop rolls around the waist. A slight complication is that the hoop rotates in an elliptical path if the waist rotates back and

In order to describe the velocity of two bodies after they collide, Newton developed a phenomenological equation known as ‘Newton’s experimental law’ (NEL). In this way, he was able to practically bypass the complication involving the details of the force that occurs during the collision of the two bodies. Today, we use NEL together with momentum conservation to predict each body’s velocity after collision
