Physic-Energy Flashcards
To know key terms on what energy is and it's types, the laws behind how energy behaves, and how to calculate it
Define
Kinetic Energy
The energy that an object possesses due to its motion.
What is the law of Conservation of energy
“Energy cannot be created, nor destroyed, only transferred”
Formula for
Work
Work done = force × distance
Define
Work
Work done is the energy transferred when a force is applied to an object.
Define
Gravitational potential energy
The energy stored in an object due to its height above a gravitational body
Define
Elastic potential energy
The energy stored in an object due to its shape
Define
Thermal Energy
The energy stored in an object based on it’s temperature and heat
What are the three mechanisms, thermal energy transfers
- Conduction
- Convection
- Radiation
At what temp will particles stop virbrating
Absoulute 0(−273.15 °C)
Define
Chemical Energy
The potential energy stored in the bonds between atoms in a molecule.
Define
Nuclear Energy
The energy stored in the nucleus of an atom.
Define
Electrical energy
The energy caused by the movement of electrons.
Define
Watts
The rate of energy transfer in electrical devices
Formula for
Watt
Watts = Energy / Time
Note:Energy should be in joules and time in seconds
Formula
Kilowatt-Hours
Kilowatts * Time
