Velocity-Time Graphs - GCSE Physics

This video introduces velocity-time graphs. Not to be confused with distance-time graphs, velocity-time graphs show the object's velocity with time. On the x-axis we have time and on the y-axis we have velocity. The gradient of a velocity-time graph gives the acceleration of an object. This is because the gradient is given by the change in the y-axis (velocity) divided by the change in the x-axis (time). This means that the gradient is the change in velocity divided by the change in time i.e. acceleration. A steeper gradient means that an object is travelling at a greater acceleration. The area underneath a velocity-time graph gives the displacement of the object. This is because velocity = displacement/time. Therefore displacement = velocity x time i.e. the area under the graph. Remember that: The gradient is equal to its acceleration The area under the line is equal to its displacement Thanks for watching, Lewis Relevant for GCSE Physics 9-1 in the following exam boards: AQA (including Trilogy) Edexcel CCEA OCR A OCR B WJEC CIE (Cambridge International Examinations) IGCSE (Higher only) Edexcel International IGCSE _____________________________________ MY PHYSICS WEBSITES Find even more videos organised by exam board and topic at: GCSE Physics Online ► https://www.gcsephysicsonline.com A Level Physics Online ► https://www.alevelphysicsonline.com MY YOUTUBE CHANNEL Your support in watching this video has been invaluable!
