Potential energy - PowerPoint PPT Presentation
Kinetic Energy
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
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 .

What are Kinetic and Potential Energy?
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.
