Instructions KEYWORDS AND CONCEPTS Mechanics – oldest physical science that deals with both stationary and moving bodies under the influence of forces Statics – branch of mechanics that deals with bodies at rest Dynamics – branch that deals with bodies in motion Fluid mechanics – defined as the science that deals with the behavior of fluids at rest or in motion Fluid statics – the study of fluids at rest Fluid kinematics – study of fluids in motion where pressure forces are not considered Fluid dynamics – branch of science if pressure forces are considered for fluids in motion Hydrodynamics – study of motion of fluids that are practically incompressible Hydraulics – deals with liquid flows in pipes and open channels Fluid – a substance in the liquid or gas phase Mass density – amount of mass per unit volume of that object or substance Weight density – weight of unit volume of that object or substance Pressure – defined as the ratio of force applied per area covered Buoyancy – tendency of a fluid to uplift a submerged body, because of the up-thrust of the fluid Uniform flow – which the velocities of the liquid particles at all sections of a pipe or a channel are equal Non-uniform flow – the velocities of liquid particles at all sections of a pipe or channel are not equal TANAUAN CITY COLLEGE NSCI02 /MODULE NUMBER 6 PHYSICS FOR ENGINEERSStreamline flow – which each liquid particle has a definite path and the paths of individual particles do not cross each other Turbulent flow – It is the parameter that describes the vibration. Steady flow – the quality of liquid flowing per second is constant Unsteady flow – the quality of liquid flowing per second is not constant Compressible flow – the volume of a fluid and its density changes during the flow Incompressible flow – the volume of a flowing fluid and its density does not change during the flow Rotational flow – the fluid particles also rotate about their own axes while flowing Irrotational flow – the fluid particles do not rotate about their own axes and retain their original orientation One-dimensional flow – the streamlines of its moving particles may be represented by straight line Two-dimensional flow – whose streamlines may be represented by a curve Three-dimensional flow – whose streamlines may be represented in space along three mutually perpendicular directions Harmonic motion – periodic motion in which the displacement is symmetrical about a point Simple harmonic motion – harmonic motion that repeats indefinitely Damped harmonic motion – harmonic motion that gradually diminishes its energy and slows down until it is already at full stop. Driven harmonic motion – harmonic motion that uses an outside force to continue its movement Period – amount of time taken for the motion to repeat itself Frequency – number of times the motion is repeated per unit of time Amplitude – extreme magnitude of displacement Angular frequency – parameter that describes the vibration Phase angle – amount of shift from the standard sine function Pendulum – object that swings back and forth between two angular positions Simple pendulum – attached to a suspended material with mass negligible compared to that of point mass Physical pendulum – the entire body swings back and forth, that does not pass through its center of mass Torsion pendulum – the suspended material does not swing
