Physics SSS2 First Term

Sub Theme: Interaction of matter, space and time

WEEK 1

Position, Distance and acceleration

Performance Objectives

Students should be able to;

1. Use a Cartesian system to locate the position of an object on the x-y plane.
2. Define distance, position and displacement

Position

Content

The position is the location of a point/object with respect to a reference point. The position of a point in space is defined in terms of the distance of the point from the reference point (which is sometimes called ORIGIN). In physics, the position of an object in space is represented in a coordinate system. There are three main types of coordinate system for representing the position of an object in space:

1. Cartesian coordinate system
2. Spherical coordinate system
3. Cylindrical-coordinate system
