Topics

• In uniform motion a body covers equal distances in equal intervals of time; its distance–time graph is a straight line.
• The slope of a distance–time graph gives the speed; a steeper line means a faster car.
• When the car speeds up, its distance–time graph curves upward and its velocity–time graph is a rising straight line.
• Uniform acceleration means velocity changes by equal amounts in equal times: a straight sloping line on the v–t graph.
• When the car brakes, its velocity falls to zero: the v–t line slopes down and the s–t curve flattens out.
• The area under a velocity–time graph equals the distance travelled; for uniform speed it is the rectangle v × t.
• The slope of a velocity–time graph is the acceleration; a horizontal line means zero acceleration.
• On a round trip the car returns to its start, so its displacement is zero even though the distance travelled is not.
• Velocity has direction: on the return leg the velocity is negative and is drawn below the time axis.
