Lesson: Work Done by a Force Expressed in Vector Notation Mathematics
In this lesson, we will learn how to calculate the work done by a constant force vector acting on a body over a displacement vector using the dot product.

A particle moves in a plane in which and are perpendicular unit vectors. A force acts on the particle. The particle moves from the origin to a point with the position vector m. Find the work done by the force.
A force acts on a particle, causing a displacement . If the work done by the force is 0.02 J, what is the value of ?
A particle moved from point to point along a straight line under the action of the force . During this stage of motion, the work done by the force was 106 units of work. The particle then moved from to another point under the effect of the same force. During this stage of motion, the work done by the force was units of work. Determine the two constants and .
