Study Notes
Position
- Position is the location of an object in space relative to a reference point.
- It is often described using coordinates, such as (x, y, z) in three-dimensional space.
- The reference point, or origin, is typically considered (0, 0, 0).
Frame of Reference
- A frame of reference is a random set of dimensions that represents the position and motion of an object.
Coordinate Systems
- Cartesian coordinates are commonly used to describe position in two dimensions (x, y) and three dimensions (x, y, z).
Displacement
- Displacement is the change in the position of an object.
Example
- If a car is parked at (2, 3) on a grid map where each unit represents 1 kilometer, the car is 2 kilometers east and 3 kilometers north of the origin.
Position
- Position refers to the location of an object in space relative to a reference point.
Key Features
- Can be described using coordinates, such as (x, y, z) in three-dimensional space.
- The reference point, also known as the origin, is usually considered (0, 0, 0).
- Helps in understanding where an object is located and how it moves.
Example
- If a car is parked at (2, 3) on a grid map where each unit represents 1 kilometer, the car is 2 kilometers east and 3 kilometers north of the origin.
Definition
- Position is the specific point in space where an object is located relative to a reference point.

Frame of Reference
- A random set of dimensions wherein the position and motions of an item are represented.
Coordinate Systems
- Commonly used systems include:
- Cartesian coordinates (x, y) in two dimensions.
- Cartesian coordinates (x, y, z) in three dimensions.
Motion
- The change in the position of an object.
