6.5.2 work done and energy transfer Flashcards
1
Q
What is work done?
A
when a force causes an object to move through a distance, this is when work is done on the object.
2
Q
What is the equation for work done?
A
work done (W, Joules, J) = force (F, in newtons, N) x distance (s, in metres)
3
Q
1 joule = ?
A
1 newton- metre (one joule of work is done when a force of one newton causes a displacement of one metre)
4
Q
What happens when work done acts against the frictional forces of an object
A
It causes a rise of temperature within the object
