Which of the following is the formula for work?

47% Answer Correctly

	\(W = {\vec{F} \over \vec{d} }\)
	\(W = \vec{F}\vec{d}\)
	\(W = {F}{d}\)
	\(W = {{F}\over{d}}\)

Solution

Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meter (Nm), work is calculated by multiplying force times displacement: \(W = \vec{F}\vec{d}\)
