Key Concepts

Dot Product

The dot product is a mathematical operation that takes two vectors and returns a scalar. In physics, it is used to calculate work by multiplying the magnitude of the force by the displacement and the cosine of the angle between them, ensuring that only the effective component of the force is considered.

Displacement

Displacement is a vector quantity that measures the change in an object's position. It is the straight-line distance from the initial to the final position, and when combined with force in the work formula, it determines the magnitude of the energy transferred.

Work

Work is the energy transferred to or from an object via the application of force along a displacement. It is defined as the dot product of the force and displacement vectors, meaning that only the component of the force acting in the direction of the displacement contributes to the work done.

Force

Force is a vector quantity that represents an interaction which can change the state of motion of an object. It has both magnitude and direction, and in the context of work, it is the driving factor applied to move an object.
