Question

what is a joule, which is a unit of work, equal to?
a newton times a second
a newton times a meter
a newton divided by a meter
a newton divided by a second

Explanation:

Work is calculated as \(W = F\times d\), where \(F\) is force (unit: newton) and \(d\) is distance (unit: meter). So the unit of work (joule) is newton - meter.

Answer:

a newton times a meter
