Module 3

• movements of objects in a space with two or three coordinate axes, respectively. Motion in 2 to 3 dimensions
• In two-dimensional motion, objects can move both horizontally and vertically. This common in scenarios like projectile motion, where an object is launched into the air moves under the influence of gravity. Horizontal/Vertical components
• Is often described using vectors, which have both magnitude and direction. Vector representation
• In three dimensional motion, we introduce a third axis z-axis to the traditional x and y axes found in two dimensions. XYZ coordinates
• Motion in 3 dimensions is more complex than in two dimensions. Objects can follow curved paths, helical trajectories, or even orbits. Complex trajectories
• Describing the position and movement of objects in three dimensions requires a spatial awareness. spatial awareness
• A projectile is a body which is given an initial velocity and then allowed to move under the influence of gravity only.
• Once a projectile is released, it will trace a curvilinear (nonlinear) path called trajectory.
• Projectile motion is combination of horizontal motion with constant velocity and vertical motion with constant acceleration.
