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.
Learn the difference between distance, displacement, speed and velocity, and how to calculate distance, speed and acceleration.
Watch how the graphs of Position vs. Time and Acceleration vs. Time change as they adjust to match the motion shown on the Velocity vs. Time graph. In this simulation you adjust the shape of a Velocity vs. Time graph by sliding points up or down.
The motion of any moving object can be described by its speed– time graph. Data from the graph can be used to calculate acceleration, the distance travelled and the average speed for the...
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.
Key learning points. A velocity-time graph shows how velocity changes with time. Acceleration is equal to the gradient of a velocity-time graph. A falling line shows decreasing velocity called deceleration, which is a negative acceleration.
