definition of work

 In physics, work is a measure of energy transfer that occurs when a force is applied to an object, causing it to move in the direction of the force. The mathematical formula to define work is: W = F ⋅ d ⋅ cos ⁡ ( θ ) W = F \cdot d \cdot \cos(\theta) Here: W W - represents the work done, measured in joules (J). F F - is the magnitude of the applied force, measured in newtons (N). d d -  is the displacement of the object, measured in meters (m). θ \theta - is the angle between the direction of the applied force and the displacement vector. Work is only done when there is displacement and a component of the force acts along the direction of the displacement. If θ = 0 ∘ \theta = 0^\circ θ = 0 ∘ , the force and displacement are perfectly aligned, and cos ⁡ ( 0 ∘ ) = 1 \cos(0^\circ) = 1 cos ( 0 ∘ ) = 1 , meaning all the force contributes to work. If θ = 9 0 ∘ \theta = 90^\circ θ = 9 0 ∘ , no work is done since cos ⁡ ( 9 0 ∘ ) = 0 \cos(90^\circ) = 0 cos ( 9 0 ∘ ) = 0 . This form...
