Item no.: F05 Introduction With the development of sound and hearing technology, such mechanical or digital device, widely applied in our daily lives, has attracted public interest and attention. By way of air medium, sound source, for example, conveying some specific frequency and amplitude could be easily detected by human ears, even the intensity is
Item no.: F14 Introduction it is generally designed as a venturi meter to measure the flow rate or flow velocity, includes liquid or gas, inside the piping system of varying cross-section. Base on the conservation of flow as well as mechanical energy (Bernoulli equation), i.e. V(flow velocity) x A( cross-section area) =constant and P (hydraulic
Item no.: F03 Introduction Why does spring water come out the ground continuously? How does a ship bear large loads while sail on the sea? How did Archimedes test and figure out the material of pure gold? How does a magician put a needle through a ballon without explosion? That is due to some special
Item no.: F07 Introduction These experiment kits is designed to demonstrate the dynamic projected motion, which provides the user an useful manner to understand the conservation of mechanical energy. Here the transformation of potential/ kinetic energy in elastic/inelastic collision will be clearly discussed. When the steel ball is jetted horizontally with three different velocities in
Item no.: F02 Objectives With the aid of optical timers, slider’s acceleration to verify Newton’s Second Law of Motion could be determined. Slider’s acceleration along the component of inclined plane, ‘gsinθ ‘ is found to be dependent on the inclined angle, but irrelevant to slider’s mass. Conservation of momentum in elastic and inelastic collisions. 4.Kinetic
