Definition: work done on a body by a force. the work done on a body by a force is dependent on the force that acts on the body and the distance that the body moves in the direction of that force according to the formula 𝑊 = 𝐹 ⋅ 𝑑 (𝜃), c o s where 𝐹 is the magnitude of the force, 𝑑 is the magnitude of displacement of the body.

Lesson Work Done By A Force Expressed In Vector Notation Nagwa In this lesson, we’ll learn how to calculate the work done by a constant force vector acting on a body over a displacement vector using the dot product. remember, work is done when a force causes a body to move over some distance. and in its most simplest form, it can be calculated by finding the product of those two measures, force times. In vector notation, work is expressed as a scalar quantity, meaning it has only magnitude and no direction. the unit of work is joules (j) in the si system, and it is written as w = f ⋅ d ⋅ cos (θ), where f is the magnitude of the force, d is the magnitude of the displacement, and θ is the angle between the two vectors. The force is constant. no need for integration. if you don't like vectors, try breaking down this problem into its three components. the work done can be seen as the sum of the work done along the x, y and z components : w = f x s x f y s y f z s z. this should make it quite obvious. Calculating the amount of work done by forces. in a previous part of lesson 1, work was described as taking place when a force acts upon an object to cause a displacement. when a force acts to cause an object to be displaced, three quantities must be known in order to calculate the work.
