How to Find Acceleration in Speed-Time Graph. The gradient of the speed-time graph gives the acceleration. Example of Finding Acceleration in Speed‒Time Graph. For first 10 s, Acceleration, a = 20 m/s ÷ 10 s. = 2 m/s2 (acceleration) For last 5s, a = (0 – 20 m/s) ÷ 5 s. = –4 m/s2 (retardation or deceleration) Important Definitions of Kinematics.
The acceleration of an object can be calculated from the gradient of a speed-time graph. How to find the gradient of a speed-time graph. Worked example. Tora is training for a cycling tournament. The speed-time graph below shows her motion as she cycles along a flat, straight road.

Distance-time graphs show distance from a fixed point at different times. Distance is on the vertical axis, and time is on the horizontal axis. The gradient of the graph is the speed. A positive gradient represents the object (or person) moving away from the starting point.
Acceleration is the rate of change of displacement with time. To find acceleration, calculate the slope in each interval. Plot these values as a function of time. Since the acceleration is constant within each interval, the new graph should be made entirely of linked horizontal segments.
These lessons, with videos, examples and step-by-step solutions, help GCSE Maths students learn how to read distance-time graphs and speed-time graphs. The slope of a distance-time graph is velocity. The slope of a speed-time graph is acceleration. The following diagram shows examples of distance-time graphs.
In this explainer, we will learn how to determine speeds from distance–time graphs. We recall that, on a distance–time graph, a line through a set of points plotted on the graph represents a speed.
