Energy 1
Within a closed system, energy can change form, but the total amount of energy is constant or the same. Energy can neither be created nor destroyed.
Law of Conservation of Energy.
Chemical Potential Energy
Potential energy is stored in chemical connections. When these bonds are broken, the excess energy is seen as motion and heat.
Thermal Energy
The total kinetic energy of moving particles of matter.
Explain Rotation
happens when an object is spinning or turning on a single point.
When we talk about convection, what is a fluid?
A liquid or a gas.
What forms of energy is a byproduct of friction?
Thermal Energy
Elastic Potential Energy
When an object is either stretched out or compressed, but when you let it go it snaps back it has elastic potential energy.
Heat
The transfer of thermal energy between substances.
Energy due to motion from one location to another
Translational Kinetic Energy
the amount of energy needed to change the temperature of 1 kg of a substance by 1 degree celcius
Specific Heat
Stored Energy
Potential Energy
What two factors affect gravitational potential energy?
mass & height
During heat transfer, thermal energy travels....
from the object with the higher temperature to the object with the lower temperature.
Or Hot to cold.
What are the three types of kinetic energy?
Vibration, rotation, translational
How is thermal energy passed through conduction?
When particles of substances of different temperatures come into contact, thermal energy passes from the object with a higher temperature to one of a lower Temperature.
Occurs when an object is elevated.
Gravitational Potential Energy
Summarize the relationship between potential and kinetic energy.
When work is done on an object, the work may be changed into either kinetic or potential energy. When movement happens, it's kinetic. When a change in position (not a change in location) happens, there is a conversion to potential energy.
the transfer of thermal energy by waves
Thermal Radiation
What two factors does kinetic energy depend on?
Mass and velocity
What is conduction?
the transfer of thermal energy between particles of matter that are touching.
everything that is involved in the transfer of energy.
A system
Energy IN Motion
Kinetic Energy
What is convection?
the transfer of thermal energy by particles moving through a fluid.
form of mechanical energy that starts with a vibration in matter
Sound Energy
