The Law of Conservation of Energy says that an object with a specific potential energy, when falling will convert that energy to kinetic energy. The purpose of this lab was to prove that this occurs. The apparatus used consisted of a rotating vertical shaft, and a centered horizontal crossbar atop the vertical shaft with wingnuts and masses. A mass hanger was attached to the string and ran over a seemingly frictionless pulley system. ... When the hanger was dropped, the shaft rotated, causing the horizontal cross bar to go into rotation about the vertical shaft. The linear kinetic energy from...

... , and in 1738, published his most famous work, Hydrodynamica, which was a study of equilibrium, pressure, and velocity of fluids. He proved that as the velocity of fluid flow increases, its pressure decreases. Bernoulli's principle was an early formulation of the subsequent idea ofthe conservation of energy?. Bernoulli's Hydrodynamica was also the first attemt to explainof the behavior of gasses with changing pressure and temperature. This was the beginning ... moving particles. Bernoulli's principle was centerd around the notion that we suppose a small portion of liquid flow from one po...

... velocity is the rate of change of angular displacement and can be described by the relationship: Thus we say that the relationship between frequency and angular velocity is defined as: =2 F = 2 T Conservation of energy The energy associated with motion is called kinetic energy. The kinetic energy [K.E = ½ mv ] depends on the mass of the object and its speed. A pendulum possesses this energy. The energy stored in a system by virtue of its position or configuration ... is called potential energy. A pendulum also possesses this type of energy. When you pull the pendulum to a certain heigh...

... . First derived (1738) by the Swiss mathematician Daniel Bernoulli, the theorem states, in effect, that the total mechanical energy of the flowing fluid, comprising the energy associated with fluid pressure, the gravitational potential energy of elevation, and the kinetic energy of fluid motion, remains constant. Bernoulli's theorem is the principle of energy conservation for ideal fluids in steady, or streamline, flow. Bernoulli's theorem implies, therefore, that if the fluid flows ... horizontally so that no change in gravitational potential energy occurs, then a decrease in fluid pres...

... water leaving. Using the equation, mass flow rate out is equal to the change in mass over the change in time, we get that the change in time is 1.734seconds. Conservation of Momentum Assumptions: • Deceleration is constant. • Exit velocity is constant. • Neglect all drag. • No sloshing. • mo = 2.266 kg Using: First term: This term goes away because ... water, analyzed according to our assumptions. Adding drag as a consideration to the momentum equation gives us With the cylindrical shape of our craft a drag coefficient of .91 would be used for the L/d of 20. Energy Equation Us...
