Energy Energy can neither be created or destroyed‚ only changed into different forms. Energy is only useful when it can be converted into different forms. Energy is often dissipated - spread out and lost. 9 types of energy: Thermal (heat) - flows from hot to cold objects Kinetic (movement) - anything that is moving has this Light - from the sun‚ light bulbs et cetera Elastically potential - when things are stretched Gravitational potential - anything that can fall Electrical - whenever

Chapter 10 Phase Transformations in Metals: development of microstructure and alteration of mechanical properties 1. Phase Transformations: a change in the number and/or character of the phases that constitute the microstructure of an alloy *phase: a homogenous portion of a system that has a uniform physical and chemical make up. *Stages of phase transformation 1. Nucleation: the formation of very small particals‚ called nuclei‚ of the new phase‚ which are capable of growing. 2. Growth: The

An investigation into the specific heat capacity of a solid Introduction: In this experiment I investigated the specific heat capacity of brass and aluminium‚ in order to do this I arranged a series circuit with a heater‚ the heater would go inside the brass and aluminium and heat it for an amount of time in which I decided‚ I also used the voltmeter in parallel. This arrangement made me able to arrange the equation VIT= mcΔθ‚ since the electrical energy in would be equal to the mass times the

I’m pretty sure we have had this discussion before so i’ve got one of my old copypastas from a previous thread. >> Force travels through solid objects at roughly the speed of sound in that object‚ if you force a piece of an object to move at greater than the speed of sound through that medium it will simply tear whatever is holding it together without transmitting force to the surrounding structure. this gives a kind of hole punch effect if the projectile is moving faster than the speed of

On a beautiful summer day‚ one of the most relaxing things to do is watch the steady rise and fall of the ocean waves. Though this motion seems calm and harmless‚ it is‚ in reality‚ a great force of nature. The force becomes even stronger when it is mixed with one of nature’s greatest disasters: earthquakes. When these two great forces collide‚ structure and society are greatly impacted. Though an earthquake can happen at almost anywhere and anytime in the world‚ they all start out in the same way

http://hyperphysics.phy-astr.gsu.edu/hbase/class/phscilab/dens.html Archimedes’ principle states that the buoyant force experienced by a submerged object is equal to the weight of the liquid displaced by the object. Experimentally this appears in the fact that the submerged object apparently weighs less by an amount equal to the weight of the liquid displaced. The buoyant force can be expressed as http://hyperphysics.phy-astr.gsu.edu/hbase/pbuoy.html#arch3 Buoyancy Buoyancy arises from the

CLASSIFICATION OF VIBRATION Vibration can be classified in several ways. Some of the important classifications are as follows. • Free Vibration. If a system‚ after an initial disturbance‚ is left to vibrate on its own‚ the ensuing vibration is known as free vibration. No external force acts on the system. The oscillation of a simple pendulum is an example of free vibration. • Forced Vibration. If a system is subjected to an external force (often‚ a repeating type of force)‚ the resulting vibration

The electricity requirements of the world including India are increasing at alarming rate and the power demand has been running ahead of supply. It is also now widely recognized that the fossil fuels and other conventional resources‚ presently being used for generation of electrical energy‚ may not be either sufficient or suitable to keep pace with ever increasing demand of the electrical energy of the world. Also generation of electrical power by coal based steam power plants or nuclear power plants
