The study of motion is kinematics, but kinematics only describes the way objects move—their velocity and their acceleration. Dynamics considers the forces that affect the motion of moving objects and systems. Newton’s laws of motion are the foundation of dynamics.
• Examples of motion in one dimension: – Displacement, velocity, acceleration, free fall, and …. In a straight line. • An example of motion in two dimension (x and y axis) is projectile motion. • An example of a three dimensional motion (x, y and z axis) is motion of a bird or an insect since it is flying in space. 12 CMPE department-TIU
We extend our definitions of position, velocity, and acceleration for an object that moves in two dimensions (in a plane) by treating each direction independently, which we can do with vector quantities by resolving each of these quantities into components.

Motion not confined to a plane, such as a car following a winding mountain road, is described by three-dimensional kinematics. Both two- and three-dimensional kinematics are simple extensions of the one-dimensional kinematics developed for straight-line motion in the previous chapter.

Mar 28, 2024 · Using vectors to describe motion in two dimensions. We can specify the location of an object with its coordinates, and we can describe any displacement by a vector. First, consider the case of an object moving with a constant velocity in a particular direction.
