|
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
|
