GCSE; AQA; Using and interpreting graphs - AQA Speed-time and velocity-time graphs. Using graphs is not just about reading off values. In real-life contexts, the intercept, gradient and area ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

The x 0 is the starting postion (at t = 0) and v 0 is the velocity at time zero. So, for this case, ... distance should be proportional to time squared. Let's make another graph.

The slope of the velocity-time graph is the average acceleration. You can see the fitting equation gives an average acceleration of 6 x 10 4 m/s 2. Impressive ...

Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact. The gradient of speed-time and velocity-time graphs represent acceleration.
