Position vector in a plane

The position vector in of an object moving in the xy plane is 𝐫 ⃗ = x 𝒊 ⃗ + y 𝒋 ⃗. All position vectors start from the origin O of coordinates and directed towards the position of the object at the considered instant. The magnitude of the position vector is ‖𝐫 ⃗ ‖ = OM = √(𝐱^𝟐 + 𝐲^𝟐 ). The magnitude of the position vector at a certain instant represents the distance separating the object from the origin of coordinates at this instant. We are going to solve an exercise about the position vector at the end of the video.
