work power and energy Flashcards
what are the two factors that determine find the amount of work done
the magnitude of force applied,
the distance the object moves
Define energy
The ability to do work
define Power
The rate at which the work is done
what is the SI unit of power
WATT
in the CGS system the unit of work is __
erg
The SI unit of energy is
Joule
Define kinetic energy
When the body is in motion
What are the different types of kinetic energy
linear or translation kinetic energy
rotational kinetic energy
vibrational kinetic and I G
if the __ is a moving object is doubled its kinetic energy is also __
mass , doubled
if the velocity of the moving object is ___kinetic energy ___four times
doubled , increases
SI unit of potential energy is?
Joule
Law of Conservation of energy
Energy can neither be created nor destroyed but it has been transformed from one form of energy to another form of energy
