Exam Tips
- Always read the axes carefully before calculating gradient — note the scale and units
- Horizontal sections: if asked what this means, say "the [variable] is not changing" (e.g. "the object is stationary", "the temperature is constant")
- Steeper does not always mean larger number — check scales! A gentle-looking line might represent a very high speed if the x-axis scale is compressed
- Container filling: match the shape of the container cross-section to the shape of the graph — wider cross-section = shallower gradient at that height
- Comparing two graphs: the steeper line represents a faster rate; if they cross, they are equal at that point
- Write units: gradient without units loses marks in context questions
- Negative gradient on a distance-time graph means returning, not going backwards in time
