string to a trolley. The trolley was attached to a length of ticker-timer tape‚ which passed through a ticker-timer‚ connected to an AC power supply. The ticker-timer tape‚ trolley and string were all lined up horizontally‚ to reduce errors due to friction in the final results. A slotted mass of 50g was placed on the mass carrier‚ and 250g on the trolley. The trolley was then pulled back so that it was a distance from the edge of the table‚ at this point the trolley was released and the

This paper is to identify possible sources of intergenerational friction‚ and to describe how this differences could be managed in occupational setting. Today is the time when multiple generations are working side by side. Each generation has some distinctly different expectations and perceptions about what their working environment will provide and how they should behave as employees. Therefore‚ many organizations today are challenged by intergenerational issues they have never experience before
