Study Notes
Position in Physics
- Position is often discussed in relation to the x-axis and y-axis in a two-dimensional coordinate system.
Displacement in Physics
- Displacement refers to the change in position of an object, calculated as the difference between final and initial positions, represented as a vector quantity.
Origin in x-y Graphs
- The origin in the context of an x-y graph is the point where the x-axis and y-axis intersect, typically denoted as (0,0). It serves as the reference point for measuring positions.
Definition of Position in Physics
- Position is defined as the location of an object in space relative to a chosen reference point or origin, usually described by coordinates in a chosen coordinate system.
Latitude and Longitude
- Latitude and longitude provide a geographic coordinate system defining position on Earth, where latitude measures north-south position relative to the equator and longitude measures east-west position relative to the Prime Meridian.
Position-Time Graphs
- In a position-time graph, a downward sloping diagonal line represents an object moving back towards the origin or decreasing its position over time.
Stationary Object in Position-Time Graph
- When an object is not moving from the origin, its position-time graph appears as a horizontal line parallel to the time axis, indicating constant position.
Positive y-Value in x,y Position
- A positive result of y in a traditional x,y position indicates that the point lies above the x-axis, suggesting a positive vertical displacement from the origin.
