Motion in Three Dimensions
Motion in three dimensions involves an object's movement through space, described using three perpendicular axes: x (horizontal), y (vertical), and z (depth). In Newtonian mechanics, the laws of motion dictate how objects respond to forces. For instance, when you throw a ball, it travels forward (x), rises or falls (y), and can move away or towards you (z). By analyzing an object's position, velocity, and acceleration in these three dimensions, we can predict its future behavior when influenced by various forces, such as gravity or friction. This framework helps us understand everything from everyday objects to celestial mechanics.
