Energy Flashcards
Force applied to move a object over some distance
W= F x D
Work
The capacity to do work or produce change
Energy
Forms of Energy
Heat Light Electrical Nuclear Chemical
Energy can neither be created nor destroyed, only changed in form
Law of conservation of energy
Final form for most energy
Heat
What are the two types if mechanical energy
Kinetic and potential
Types of kinetic energy
Translational rotational and vibrational
What is kinetic energy
Energy of motion
What is potential energy
Energy of position or stores energy
Types of potential energy
Absolute and relative
What is absolute
Stored energy
What is relative
Energy of position
What are two types of collision
Elastic and inelastic
What is elastic
Doesn’t lose energy
What is inelastic
Loses energy usually in the form of heat
What does entrupy
Disorder
All change tends towards minimum energy and maximum energy
2nd law of thermodynamics
Energy content for a substance, energy stored in its formation
Enthalpy
