In this discussion, we're going to learn how to calculate the resultant motion from two types of movement at the same time: vertical motion and horizontal motion. The example we're using is a boat crossing a river, where its motion is influenced not only by how fast it rows but also by the flow of the river.

This is an interesting scenario because it shows how two different motions combine to create a single resultant motion. Here, we'll break the motion down into simpler components, figure out the impact of each component, and then find the resultant using vector principles.

By understanding how to calculate resultant motion, we also learn that the direction and speed of an object are influenced by the interaction of two or more forces. For example, a boat crossing the river might not land directly across from where it started because of the river current.

This topic not only helps us grasp basic motion concepts in physics but also shows how these principles apply in real life, like navigating boats or planes affected by wind or currents. So, besides learning physics, we're also building logical thinking and understanding how different factors influence an object’s movement.
