Work Energy Principles Flashcards
(4 cards)
1
Q
What is the Work-Energy Principle?
A
The net work done on an object is equal to its change in kinetic energy.
2
Q
formula for the Work-Energy Principle?
A
W=dke=.5mv² – .5mu²
3
Q
In the Work-Energy Principle, what does “work done” refer to?
A
The energy transferred to or from an object via a force causing displacement.
4
Q
Does the Work-Energy Principle apply if friction or other non-conservative forces act?
A
Yes, but the work done by those forces may also convert kinetic energy into other forms like heat.
