'Potential energy' diaporamas de présentation

Kinetic Energy. energy of the motion of an object. = m x V 2 2. m = mass V = velocity. The location on the track where the train has the greatest potential energy is. Kinetic. K inetic energy energy of a moving object. When does a toy race car have kinetic energy?

Group Work The 2004 Tour de France’s Alpe d’Huez time trial was a climb with its finish 1200 m higher than the start. The winner, Lance Armstrong, and his gear had a combined mass of 84 kg . The work Lance had to do was ( 84 kg )( 9.8 N/kg )( 1200 m ) = about 10 6 J .

Hydro-electric power generation Snowy Mountains Scheme. The Snowy Mountains Scheme consists of 7 power stations - Murray 1, Murray 2, Guthega, Blowering, Tumut 1 (located 366 metres below ground level), Tumut 2 (located 244 metres below ground level), and Tumut 3.

HEATING AND COOLING CURVES . Concepts. What are some things that happen as we heat a sample up?. Solid  Liquid  Gas Melting, Evaporating Increase in entropy. What is heat? How is heat different from temperature? . Heat is a measure of kinetic energy

Potential and Kinetic Energy ENERGY IN GENERAL Energy: the ability to do work It can be found in many forms. Energy can be converted from one form to another. Although energy can be changed, it cannot be created nor destroyed. Potential Energy Stored energy

Chemical Bonds. The interaction between 2 atoms may result in the formation of a chemical bond whereby 2 atoms are chemically linked to one another 2 major types Ionic Covalent Atoms bond with one another to become stable

What are Kinetic and Potential Energy?. What is ENERGY?. Energy is the ability to do work. Everything that happens in the world uses energy! Most of the time we can’t see energy, but it is everywhere around us!. Energy…. is NEVER created or destroyed! can only be STORED or TRANFERRED.

The Law of Conservation of Energy. Energy cannot be created or destroyed; it may be transformed from one form into another, but the total amount of energy never changes. What is energy?. “the ability to do work” The combination of energy and matter make up the universe:
