1.7.2 Work done

To calculate the work done by a constant force, the magnitude of the force must be known.

What else needs to be known to calculate the work done?

	Distance that the force moves the object in the direction of the force	Time for which the force acts on the object
A	$✓\checkmark$	$✓\checkmark$
B	$✓\checkmark$	$×\times$
C	$×\times$	$✓\checkmark$
D	$×\times$	$×\times$

where $✓\checkmark$ = needed, $×\times$ = not needed.
