Question

one joule equals the amount of work that is done when 1 n of force moves an object over a distance of
a 1 cm.
b 1 m.
c 1 km.
d 1 mile.

Explanation:

Work is calculated using the formula \(W = F\times d\) (where \(W\) is work, \(F\) is force, and \(d\) is distance). The unit of work in the SI system is the joule (\(J\)). When \(F = 1\space N\) and \(W=1\space J\), substituting into the formula \(1\space J=1\space N\times d\), we get \(d = 1\space m\) (since \(1\space J = 1\space N\cdot m\)).

Answer:

B. \(1\space m\)
