6.8 A Potential and Kinetic Energy

​a group of interacting or interdependent pieces forming a complex whole

​all factors or variables that make up an experiment

​set of things or parts all related

​force is added to systems to make them work or do something

​the ability to use force to move an object over a distance or to cause a change in matter

​can be measured using Joules (J)

​unit used to measure energy

​how much energy is needed for a change to happen in a system

​represented by J

​Examples:

• ​mechanical

• ​light

• ​sound

• ​electrical

• ​thermal

• ​chemical

​change of energy from type/form to another

​energy cannot be created or destroyed

• ​Law of Conservation of Energy

​Potential Energy

​Kinetic Energy

​All types of energy can be categorized using the two

​energy stored in an object

​energy waiting to happen

​has the potential/possibility to move but has not yet

​energy of motion

​only matter in motion has kinetic energy

​all of the potential energy and kinetic energy of a system

​TE = PE + KE
