1.7.2 Work done

To calculate the work done by a force on an object, the size of the force must be known.

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

the distance the force moves the object is needed ( $✓\checkmark$ ); the time for which the force acts is needed ( $✓\checkmark$ )

the distance the force moves the object is needed ( $✓\checkmark$ ); the time for which the force acts is not needed ( $×\times$ )

the distance the force moves the object is not needed ( $×\times$ ); the time for which the force acts is needed ( $✓\checkmark$ )

the distance the force moves the object is not needed ( $×\times$ ); the time for which the force acts is not needed ( $×\times$ )
