FREE FALL AND CONSERVATION OF MECHANICAL ENERGY ABSTRACT Free fall is defined as the ideal falling motion of an object that is subject only to the earth’s gravitational field. To prove the law of conservation of energy‚ the free fall motion of an object can be represented through 3 different analyses; position of the object vs. time‚ velocity of the object vs. time‚ and acceleration of the object vs. time. It is observed in this ball toss experiment‚ at any point during the free fall period‚

Solar Energy Topics Solar technologies use the sun’s energy and light to provide heat‚ light‚ hot water‚ electricity‚ and even cooling‚ for homes‚ businesses‚ and industry. More basic information about solar is also available. Solar Technologies Photovoltaics (PV) Photovoltaic solar cells‚ which directly convert sunlight into electricity‚ are made of semiconducting materials. The simplest cells power watches and calculators and the like‚ while more complex systems can light houses and

Flywheel energy storage works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. The energy is converted back by slowing down the flywheel.Flywheel energy storage system is one form of energy storage devices. It is basically a rechargeable battery. It is used to absorb electric energy from a source‚ store it as kinetic energy of rotation‚ and then deliver it to a load at the appropriate time‚ in the form that meets the load needs
