Study Notes
Motion Graph Analysis
- The graph displays a vehicle's speed over time.
- Initial phase: Constant acceleration
- Second phase: Constant speed
- Third phase: Constant deceleration
- Fourth phase: At rest
Acceleration Phases
- Initially, the vehicle accelerates at a constant rate.
- The speed increases linearly during the constant acceleration phase.
- The vehicle maintains a constant speed for a period of time.
- The vehicle decelerates at a constant rate, decreasing its speed linearly.
- Finally, the vehicle comes to a complete stop, represented by zero speed.
Time Intervals
- The graph shows different time intervals for each phase, indicating the duration of each motion type.
- The horizontal axis represents time (seconds).
- The vertical axis represents speed (meters per second).
