Study Notes
Motion
- Motion occurs when an object changes position relative to a fixed point.
- Time is usually measured in seconds for motion events.
- Graphs display information visually.
Motion Graphs
- In motion graphs, time is usually shown on the x-axis.
- Distance is measured in meters.
- The slope of a distance-time graph shows the speed of an object.
Speed and Displacement
- Speed is the rate of change of distance over time.
- Displacement is the distance and direction of the change in an object's position.
- Displacement is a vector quantity, including both magnitude and direction.
- Speed is a scalar quantity, only including magnitude not direction.
