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

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 ...

At one point in the past, I was a teenager. Hard to believe, I know, but it's true. During that time, I thought about teenager things. In particular, I recall thinking about and wanting a super ...

The x 0 is the starting postion (at t = 0) and v 0 is the velocity at time zero. So, for this case, I will release the cart from rest (hopefully) so that the v 0 term will be zero.

A negative gradient shows the rate of “slowing down” or deceleration. Velocity-time graphs show velocity on the vertical axis. Acceleration is still represented by the gradient. Key fact The ...
