Mechanical Energy By: Chad Lally, Mitchell Heller, & Kaitlin Plank
Mechanical Energy The energy acquired by the objects upon which work is done Can be both potential and/or kinetic energy Objects have mechanical energy if they are at some position relative to a zero potential energy position Mechanical energy is the energy possessed by an object due to its motion The sum of the potential and kinetic energy of an object is the amount of its total mechanical energy
The bowling ball is doing work on the pins therefore this is an example of mechanical energy.
Thermal Energy Jelvon Butler, Adrianna Liggins, Michael Krenn
Information Slide –The amount of movement of atoms and molecules in matter. –Heat is the way thermal energy is transferred. –Can be increased or decreased. –Can be created internally with chemical, nuclear, and electrical reactions. –Related to heat and temperature. –Also can be increased or created by external effects. –Ex. The sun.
Image Without the sun’s thermal energy, the Earth would be frozen.
Radiant Energy By: Sydney Claus, Noah Fried, Dan Weinstein
Information Measured in the SI unit of joule (Newton- meter). Radiant energy travels in electromagnetic waves. Radiant energy can be visible or invisible to the human eye. Can be represented as a particle or wave. Ex. Gamma rays, X-rays, solar radiation, infrared, ultraviolet, optical, radio, light.
Sound/Acoustic Energy By: Julie, Christopher, Ayana
Info Slide It is a type of mechanical energy Produced by sound vibrations Related to the pressure it’s vibrations cause Measured in terms of pressure and intensity using Pascals and decibels Travels in waves called sound waves Examples 1.Stereos 2.Radios 3.Vocal cords
Photos Different sound waves have different frequencies
Chemical Energy: Information Chemical energy is the most commonly used form of energy –Exothermic chemical energy allows us to use chemical energy in everyday life Stored at a basic level Chemical energy is stored in every bond between the atoms in a molecule –Molecules that break down and reform (as new molecules) results in energy Chemical compounds are composed of a simple collection of atoms, bound together –Loosened bonds = chemical reaction Examples of Chemical Energy: Batteries Photosynthesis
The diagram above shows how endothermic energy works. The fire produces chemical energy, because molecules are broken and then reformed.
Nuclear Energy By Katie Cilik, Ben Feuer, and Anthony Rizkala
Nuclear Energy Nuclear energy is energy created in a nuclear reaction. It is also called atomic energy. Examples: Nuclear fission (splitting of atoms), nuclear fusion (combining of atoms) and atomic bombs.
Picture This is a diagram of what happens during nuclear fission.
Electrical Energy By: Ashley Morgan, Jalen Jackson & Brad Holmes.
Info Energy made available from the flow of an electric charge. It has Potential Energy. When an electric charge is in an object, a force is exerted from its electric field, which causes electrical energy. Examples: Lightning, static electricity & wires.
