Energy Forms
What is the energy of movement called?
Kinetic Energy
This is a formulation of the law of conservation of energy adapted for thermodynamic processes.
First Law of Thermodynamics
This is the transfer of energy from one molecule to another by direct contact.
Conduction
Work and Energy are both measured in what unit?
Joules
Which law states that energy can neither be created nor destroyed, only transferred from one form of energy to another.
Law of Conservation of Energy
This law states that heat always moves from hotter objects to colder objects.
Second Law of Thermodynamics
This is the movement of heat by a fluid such as water or air.
Convection
Why is a person standing still and holding a box not doing work?
The object must move in the same direction as the force.
The stored energy an object possesses because of its relative position is called?
Every energy transfer involves some loss of energy, usually in the form of what?
Heat Energy
This is the transfer of heat by electromagnetic waves.
Radiation
What is the equation for Kinetic Energy?
KE=1/2mv2
Is chemical energy an example of kinetic or potential energy?
Potential Energy
No energy transfer is completely efficient and all transfers trend toward disorder which is also known as what?
Entropy
Conduction
Work is equal to what two variables multiplied together?
W= Force X Distance
W=Fd
