Potential Energy

Potential Energy • Definition and Mathematics of Work • Calculating the Amount of Work Done by Forces • Potential Energy • Kinetic Energy • Mechanical Energy • Power An object can store energy as the result of its position. For example, the heavy ball of a demolition machine is storing energy when it is held at an elevated position. This stored energy of position is referred to as potential energy. Similarly, a drawn bow is able to store energy as the result of its position. When assuming...

Potential Energy

examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example, if a force of 10 newton (F = 10 N) acts along point that travels 2 meters...

Physics Definitions

direction of a uniform vector field. For a gravitational field, the field vector is g Weight Weight is defined as the force on a mass due to the gravitational field of a large celestial body such as the Earth Gravitational Potential Energy Gravitational Potential Energy is the energy of a mass due to its position within a gravitational field. On a large scale GPE is defined as the work done to move an object from infinity to a point within a gravitational field Projectile A projectile is any object...

Air Pressure Effects the Speed of Falling Objects

force; it does not drain any energy from the object moving under it, it just converts the energy from one form to another. When the pendulum reaches either end at its highest point, all the energy is potential energy, and the kinetic energy is zero. At the bottom of the swing, the kinetic energy is maximum, while potential energy is minimized. No energy is transferred out of the system, so it must keep moving. In the presence of friction, however, energy is removed from the system in the...

Flexible work arrangements

the years of 2007 and 2016. The article details the importance of how a flexible work arrangement can open the pool or available candidates to meet the growing need of senior level positions. Additionally, this article outlines the benefits and potential pitfalls of the program (Christensen, 2005). Main Issues of Both Articles According to a Bridgespan Group white paper there will be a need to add approximately 640,000 new senior level positions between the years of 2007 and 2016. In order to achieve...

Centrifugal Pump

input power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated radially outward from the pump chasing. A vacuum is created at the impellers eye that continuously draws more fluid into the pump. The energy created by the pump is kinetic energy according the Bernoulli Equation. The energy transferred to the...
