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.
When object starts from rest and undergoes constant acceleration: Position is proportional to the square of time. Position changes result in the sequence of odd numbers. Falling bodies exhibit this type of motion (since g is constant).

In this chapter, we study speed, velocity, and acceleration for motion in one-dimension. One dimensional motion is motion along a straight line, like the motion of a glider on an airtrack.

Newton began his analysis of the cause of motion by introducing the quantity of motion: Definition: Quantity of Motion . The quantity of motion is the measure of the same, arising from the . velocity and quantity of matter conjointly. The motion of the whole is the sum of the motion of all its parts; and
