What is the LAW OF CONSERVATION OF MASS?
Mass can neither be created nor destroyed.
What is CHEMICAL ENERGY?
Stored energy found in chemical bonds. This is the "glue" that holds atoms together.
What is NUCLEAR ENERGY?
Stored energy found in the nuclei of atoms.
What is THERMAL ENERGY?
The total energy of particles in a sample of matter due to the internal motion of atoms.
What is the LAW OF CONSERVATION OF ENERGY?
Energy may change forms but it can not be created or destroyed.
What are the FIVE main FORMS of ENERGY?
Mechanical, heat, chemical, electromagnetic, and nuclear energy.
What theory did Albert Einstein develop to modify the laws of conservation of energy and mass?
Theory of Relativity
What is ENERGY?
The ability to do work.
What is the unit of work and energy?
joule (J)
What is MECHANICAL ENERGY?
The total amount of kinetic and potential energy in a system.
What does Albert Einstein's THEORY OF RELATIVITY state about mass and energy?
Mass and energy can be changed into eachother but the total amount of mass and energy must always stay the same.
What is THERMAL POLLUTION?
Waste heat that occurs in the environment.
What is ELECTROMAGNETIC ENERGY?
Energy due to light.
What is another term for potential energy?
stored energy
What is TEMPERATURE?
A measure of the average kinetic energy of the particles in a sample of matter.
What TWO FORMS of POTENTIAL ENERGY exist?
chemical potential energy and stored potential energy
What is KINETIC ENERGY?
The energy that an object has due to its motion.
What is POTENTIAL ENERGY?
The energy that an object has due to its shape or position.
The amount of kinetic energy an object has depends on its mass and _______?
velocity
What is HEAT ENERGY?
Energy that flows from something with a higher temperature (more thermal energy) to something with a lower temperature (less thermal energy).
What is the FORMULA used to calculate GRAVITATIONAL POTENTIAL ENERGY?
GPE = W x h

OR

PEg = mgh
What is GRAVITATIONAL POTENTIAL ENERGY?
This is the stored energy that an object has due to its height above the earth's surface and its weight.
What type of stored energy do plants, food, fuel, coal, and batteries have?
chemical potential energy
What is the FORMULA used to calculate KINETIC ENERGY?
KE = (mv2)/2
