Energy
The ability to cause a change or to do work.
Mechanical Energy
The sum of the total energy an object has due to its motion OR position.
Kinetic Energy
Energy of motion. This type of energy increases as speed increases.
Potential Energy
Stored energy, waiting to be used. The energy an object has due to it's position (ex: height) or condition (ex: stretch).
Gravitational Potential Energy
Type of potential energy that increases when an object's height increases. Based on place or position
Elastic Potential Energy
Type of potential energy that increases when an object is stretched (ex: rubber band, bow and arrow) or compressed (ex: a spring).
Thermal Energy
Energy that increases as temperature increases. This type of energy is always lost when energy changes form.
Electromagnetic Energy
Energy that travels in waves, such as light energy, or x-rays. Does not need to travel through matter.
Sound Energy
Energy that is carried by vibrations through a medium (including water and air).
Electrical Energy
Energy carried by an electrical current.
Chemical Energy
Energy in food and fuel; chemical bonds are broken down to release this type of energy.
Nuclear Energy
Energy that is released when an atom is split in half or when 2 atoms are fused together.
Sun
The main source of energy for Earth.
Maximum Potential Energy
Top of the highest hill on a roller coaster
Maximum Kinetic Energy
Bottom of the highest hill of roller coaster
Law of Conservation of Energy
States the energy is never created or destroyed. It only changes its form.
