Kinetic Energy Q's
This type of energy is observed by the motion of particles at the atomic level within molecules.
What is thermal energy?
Remember, thermal energy is stored in the bonds between atoms that make up molecules.
This category of energy is defined as stored energy within an object.
What is potential energy?
This is the total kinetic energy of ALL moving particles in a substance.
What is thermal energy?
Remember, temperature is the average kinetic energy of all of the particles in a substance.
In every energy transformation, a small amount of energy is given off as this, which is caused by friction and drag.
What is heat?
This is a representation of the type of energy transformation and the direction that the transformation took place.
What is an energy chain diagram?
DOUBLE
This type of energy is characterized by the behavior of molecules at the molecular level within an elastic system.
What is vibrational energy?
Know the other types of Kinetic Energy from Lesson 1.
This is the ability to do work. This also makes matter move and changes it.
What is energy?
This shows the transfer of energy from a warmer object to a cooler object
What is heat?
Remember, heat is NOT ENERGY. It is an indicator that an energy transfer has taken place.
This is the amount of heat needed to raise the temperature of a substance 1°C.
What is heat capacity?
This energy can be transferred, but it CANNOT be stored.
What is kinetic energy?
Remember, potential energy can be stored and cannot be transferred.
Radiant energy from the sun is this category of energy.
What is kinetic?
This is the term for energy an object has because of its position in Earth’s gravitational force field.
What is gravitational potential energy?
Remember, this is any object that is raised over the Earth’s Surface. Know your different types of potential energy.
This law states that “heat flows from warmer objects or regions to colder objects or regions, and the flow continues until the two objects reach the same temperature.” The energy lost and gained will be equal which will make the temperature of the objects equal.
What is the Law of Thermal Equilibrium?
Remember, this means that heat will constantly transfer between objects/spaces with different temperatures until they reach the same temperature. Same temperature, same energy, same heat.
Double
This is the transfer of heat in fluids by circulation.
What is convection?
Remember, fluids are not only liquids, but compressible gasses as well.
The exchange of heat takes place until the objects reach this two-word common ground.
What is thermal equilibrium?
This law states "we cannot create energy or destroy it".
What is the Law of Conservation of Energy?
Which form of nuclear energy pertains to the splitting of atoms?
What is fission?
Remember, fusion is when we are making two atoms into one (fusing them) at the nucleus. The neutrons(_), protons(+), and electrons(-) are subatomic particles with the neutron splitting surrounding atoms during fission.
If temperature increases, this happens to thermal energy.
What is increase?
Remember, heat IS NOT ENERGY, but the heat emitted will also increase with temperature and thermal energy because they are directly proportional.
This is when fluid particles sink and rise.
What is circulation?
TRIPLE
True or False. The three heat transfer processes can work together in any capacity.
What is the TRUTH! Conduction (a transfer of heat within an object or between two objects that are touching with different temperatures), Convection, and Radiation (a transfer of heat by the emission and absorption of electromagnetic waves) can all work together or separately in any capacity.
Kinetic energy and momentum are proportional in this way.
What is directly proportional?
Remember, when we learned about KE and braking distance, we learned that the more KE an object possessed, the longer it would take for that object to release energy to its surroundings so the more time it took for the object to stop.
This form of nuclear energy produces no pollution.
What is fusion?
Remember, we currently use the process of fission in powerplants to generate electricity.
Heat flows in this direction.
What are all directions?
This state of matter allows heat to be transferred the fastest.
What are solids?
Know why this happens.
Double
Write the velocity formula on a provided sticky note.
V= Square root (2)KE/M
Mass formula is m=(2)KE/v2
Kinetic energy= 1/2 mass times velocity times velocity
Potential Energy is mass (kg) times 9.8 times height (m).
Know the steps for calculating the first 3 formulas from Lesson 1 Slides 10-17.
