4.5.2 Work Done And Energy Transfer Flashcards
1
Q
work done equation
A
work done = force x distance (moved along the line of action of the force)
2
Q
work done unit
A
work done, W, in joules, J
3
Q
force unit
A
force, F, in newtons, N
4
Q
distance unit
A
distance, S, in metres, M
5
Q
how much work is done when a force of one newton causes a displacement of one metre
A
one joule
- 1 joule = 1 newton - metre
6
Q
what causes a rise in the temperature of the object?
A
work done against the frictional forces acting on an object cause a rise in the temperature of the object
