Kinematics

Kinematics is the study of the motion of points, objects, and groups of objects without considering the causes of its motion.

In order to describe an object's motion, you need to specify its position relative to a convenient reference frame.

A vector is any quantity that has both magnitude and direction, whereas a scalar has only magnitude.

Average velocity is defined as the change in position (or displacement) over the time of travel.

Instantaneous velocity is the velocity of an object at a single point in time and space as calculated by the slope of the tangent line.

The graphical representation of acceleration over time can be derived through the graph of an object's position over time.

Constant acceleration occurs when an object's velocity changes by an equal amount in every equal time period.

There are four kinematic equations that describe the motion of objects without consideration of its causes.

A motion diagram is a pictorial description of an object's motion and represents the position of an object at equally spaced time intervals.

Free fall is the motion of a body where its weight is the only force acting on an object.
