period of a pendulum: The relationship between Density and Time IB Physics Internal Assessment IB Physics Internal Assessment Introduction The purpose of this experiment is to investigate the relationship between density and time in a homemade pendulum. In order to investigate the phenomenon‚ the density of the hanging object is going to change‚ and by recording the time it takes the object to complete a period hanging from the pendulum. According to pendulum’s theory‚ the period should be

German born fitness leader‚ Joseph H. Pilates‚ who developed the Pilates exercise system in the 1920s. His interest in physical fitness stemmed from a determination to strengthen his own body and improve his health after an unhealthy childhood. With a background in yoga‚ Zen meditation and martial arts‚ combined with success as a gymnast‚ diver and boxer‚ he was able to devise a unique sequence of movements that worked the mind and body‚ in harmony. Joseph was convinced that his philosophy

When the balloons are rubbing together they are taking charges(electrons ) from one another. When rubbed against your hair‚ the balloon steal electrons from your hair leaving you hair positive. You hair will then become attracted to the ballon because you hair is positively charged and the balloon negatively charged. You hair will stand up even when the balloon is

* Is it possible to add heat to a body without changing its temperature? Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water‚ but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without changing its temperature
