Study Notes
Distance-Time Graphs
- Graphs plotting distance against time show motion.
- Time is plotted on the x-axis (horizontal).
- Distance is plotted on the y-axis (vertical).
- A horizontal line on a distance-time graph indicates no movement (at rest).
- A diagonal line shows constant speed.
- A steeper line represents a higher speed.
- Curved lines indicate acceleration (speed is changing).
Speed vs Velocity
- Speed is the rate of motion, focusing on the magnitude.
- Velocity is speed with direction included.
- Example: 20 m/s is speed; 20 m/s east is velocity.
Speed Graphs: Distance-Time
- Time increasing to the right on a graph means time increases.
- Distance increasing vertically on the graph means distance increases from the starting point.
- Constant speed is represented by a straight line.
- Non-moving objects have a horizontal line.
- Steeper lines represent higher speeds.
Acceleration Graphs: Velocity-Time
- Acceleration is the rate of change of velocity.
- In a velocity-time graph, the gradient (slope) of the line equals the acceleration.
- A flat line indicates no acceleration (constant velocity).
- An upward curving line represents increasing acceleration.
- A downward curving line represents decreasing acceleration or deceleration.
- A negative gradient indicates deceleration.
Analyzing Acceleration Graphs
- Graphs showing acceleration and deceleration will have different shapes.
- Using graphs to analyze motion shows constant acceleration, deceleration, increasing/decreasing acceleration, or no acceleration.
- The slope of a line on a graph shows acceleration.
