It just keeps on going, and going and going Energy It just keeps on going, and going and going

What is energy? property of objects to have the ability to do work

UNits of energy amount of energy to increase 1’C of water that has 1 gram of matter in it Joules = J

1st Law of Energy Energy can neither be created nor destroyed Energy in the universe is a constant.

2nd law Of energy Order descends into chaos, chaos will ascend back to order

Potential the amount of stored Energy in an object

Formula for Potential -PE= mass x gravity x height (meters) or Force weight (N) x Height (meters) PE= m x g h (PE= Kg x m/s/s x meters) PE= Fw x H (PE= N x m)

Kinetic -Energy of movement KE=(m x v ^2)/2 mass x veloc ^2_ 2

Energy category Kinetic: Potential: -Energy an object has due to its position, energy field and parts -Stored energy Kinetic: the amount of energy a moving object has

END

CLosure Questions Which law states order will turn to chaos, chaos will return to order? Can energy be destroyed or created? 3) A bow string being pulled back belongs to which energy category? 4) Releasing a arrow from a bow belongs to which energy category?

Energy -Ability to do work -Property in objects that can be transferred into a different form -Can not be created or destroyed

Energy Transfer Energy can convert from one state to another (heat, work, mass transfer)

Potential the amount of stored Energy in an object

Elastic Energy stored in objects that stretch

Mechanical energy of objects in motion sum of both potential and kinetic

Chemical Energy released from a chemical reaction

Nuclear Energy stored in the center of particles

Kinetic -Energy of movement KE=(m x v ^2)/2 mass x veloc ^2_ 2

Sound Form of energy from vibrations (we can hear)

Radiant Energy in the form of electromagnetic waves

electrical Energy of particles moving through a wire

Magnetic objects produce a field of attraction and repelling and give off a energy field. Depends on distance, size, and type

Gravitational stored energy in an object when it is above the earth’s surface
